Introduction
One of the fundamental principles of modern aviation security is that checked baggage should not travel without the passenger to whom it belongs. This concept, commonly known as Passenger/Baggage Reconciliation (PBR) or Positive Passenger Bag Match (PPBM), has become an essential safeguard against unlawful interference with civil aviation. Every day, millions of bags are accepted, screened, loaded, transferred, and delivered across the global airline network. Throughout this journey, airlines must ensure that each checked bag remains correctly associated with its passenger and that any discrepancy is identified before aircraft departure.
The International Air Transport Association (IATA) formalized this operational principle through Recommended Practice (RP) 1739 – Passenger/Baggage Reconciliation Procedures. The Recommended Practice establishes internationally recognized procedures for reconciling passengers and their checked baggage on international flights. Its core requirement is straightforward but critical: if a passenger fails to board an aircraft, that passenger’s checked baggage must not travel on the same flight unless it has been appropriately identified as unaccompanied baggage and subjected to the required security controls.
Passenger/Baggage Reconciliation is much more than a security check performed before departure. It is an integrated operational process involving the airline’s Departure Control System (DCS), the Baggage Reconciliation System (BRS), baggage handling systems, boarding procedures, baggage messaging, and airport security operations. During check-in, each checked bag is linked electronically to the passenger through its baggage tag and License Plate Number (LPN). As passengers board the aircraft, the Departure Control System confirms their boarding status while the Baggage Reconciliation System verifies that every loaded bag belongs to a boarded passenger. If a mismatch occurs, operational alerts are generated, allowing baggage personnel to locate, remove, or re-screen the affected baggage before departure.
The origins of RP 1739 lie in several major aviation security incidents that exposed the dangers of unaccompanied checked baggage. Following terrorist attacks during the 1980s—including the bombing of Air India Flight 182 and the Lockerbie disaster involving Pan Am Flight 103—the aviation industry recognized that baggage security required more than screening technology alone. Positive baggage matching became an internationally accepted security principle, supported by ICAO Annex 17 and subsequently incorporated into IATA Recommended Practice 1739. These historical events demonstrated that ensuring passengers and their baggage travel together provides an essential layer of protection against malicious acts involving checked baggage.
Although aviation security is the primary objective of RP 1739, the Recommended Practice also delivers substantial operational benefits. Passenger/Baggage Reconciliation improves baggage accountability, reduces baggage mishandling, supports baggage tracing, and enhances auditability. When baggage is delayed or fails to arrive, reconciliation records enable airlines to determine whether the baggage travelled, remained behind, or was intentionally removed because the passenger failed to board. This information supports more effective baggage tracing, customer service, and regulatory compliance.
RP 1739 integrates closely with numerous other IATA baggage standards. Resolution 740 governs standardized baggage tags, Resolution 751 establishes the ten-digit baggage License Plate Number, Resolution 753 defines baggage tracking events, RP 1745 standardizes baggage messaging, and Resolution 780 provides the contractual framework for interline baggage transportation. Passenger/Baggage Reconciliation serves as the operational link connecting these standards into a unified baggage security process. The License Plate Number uniquely identifies each checked bag, baggage messages communicate reconciliation status, baggage tracking records custody changes, and interline procedures ensure that reconciliation continues even when baggage transfers between multiple airlines.
Today, virtually every major international airline employs automated Passenger/Baggage Reconciliation systems integrated with modern Departure Control Systems and Baggage Reconciliation Systems. Automated barcode scanners, RFID technology, real-time baggage messaging, and integrated security systems have transformed what was once a manual matching process into a highly sophisticated digital operation. Nevertheless, the fundamental principle established by RP 1739 remains unchanged: every checked bag must be positively matched with its passenger, and no bag should fly without appropriate security verification. This principle continues to underpin international aviation security while supporting safe, reliable, and accountable baggage operations across the global air transport network.

Origin and Publication
The Need for Passenger/Baggage Reconciliation
The concept of Passenger/Baggage Reconciliation emerged from one of aviation’s most important security lessons: a checked bag should never travel without its passenger unless appropriate security procedures have been completed.
During the early years of commercial aviation, baggage acceptance focused primarily on passenger convenience and operational efficiency. Once baggage had been checked, airlines generally concentrated on ensuring that it reached the correct destination rather than verifying that its owner remained on board throughout the journey.
However, several terrorist attacks during the late twentieth century demonstrated that unchecked baggage could be exploited to conceal explosive devices when passengers intentionally failed to board after checking baggage.
One of the earliest incidents occurred in 1981, when Eastern Air Lines Flight 980 became the target of a bomb attack involving checked baggage loaded without the responsible passenger boarding the aircraft. In response, Eastern Air Lines introduced an innovative “bingo tag” system in which baggage claim stubs were manually matched with passengers before baggage was authorized for loading. Although relatively simple, this positive matching process established the operational concept that later became industry standard.
The need for formal international procedures became even more apparent following the destruction of Air India Flight 182 in 1985 and Pan Am Flight 103 over Lockerbie in 1988. Both tragedies demonstrated the catastrophic consequences of unaccompanied baggage containing explosive devices. These events prompted ICAO, IATA, airlines, airports, and regulators to strengthen baggage security requirements, leading to the widespread adoption of Passenger/Baggage Reconciliation procedures.
ICAO and IATA Cooperation
Passenger/Baggage Reconciliation developed through close cooperation between the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA).
ICAO incorporated the principle into Annex 17 – Security, establishing international Standards and Recommended Practices requiring airlines to ensure that checked baggage associated with passengers who fail to board is treated as unaccompanied baggage unless appropriate security measures have been completed.
IATA subsequently developed RP 1739 to provide airlines with practical operational guidance for implementing these ICAO requirements within everyday baggage handling processes. Rather than creating new security obligations, RP 1739 explains how airlines should integrate Passenger/Baggage Reconciliation into existing baggage acceptance, boarding, and baggage handling procedures.
Passenger Services Conference
RP 1739 forms part of the IATA Passenger Services Conference (PSC) framework governing passenger services, baggage operations, baggage security, and airline interoperability.
Within this framework, the Recommended Practice defines standardized procedures covering:
- passenger/baggage matching;
- no-show baggage;
- baggage reconciliation;
- baggage status management;
- baggage offloading;
- reconciliation terminology.
Although classified as a Recommended Practice rather than a mandatory Resolution, RP 1739 has been widely adopted because it provides practical guidance supporting both ICAO security standards and national aviation security regulations.
Historical Evolution
The original manual reconciliation procedures relied upon paper baggage claim stubs and manual comparisons performed at boarding gates.
As baggage operations became increasingly automated, Passenger/Baggage Reconciliation evolved significantly.
Modern systems now integrate:
- Departure Control Systems (DCS);
- Baggage Reconciliation Systems (BRS);
- baggage tag scanners;
- baggage messaging;
- automated loading control.
These technologies allow reconciliation to occur electronically in real time while maintaining the same fundamental principle established decades earlier.
Relationship with Aviation Security
Unlike many baggage standards that primarily improve operational efficiency, RP 1739 exists first and foremost to enhance aviation security.
Its operational objective is to ensure that no checked baggage remains aboard an aircraft after its passenger has become a no-show unless appropriate security controls have been completed.
By integrating passenger boarding information with baggage tracking records, airlines gain the ability to identify discrepancies before departure, reducing the likelihood that unauthorized or suspicious baggage will travel unnoticed.
Purpose
Protecting Civil Aviation
The primary purpose of RP 1739 is to protect civil aviation by ensuring that every checked bag can be positively associated with a boarded passenger or, where necessary, treated as properly screened unaccompanied baggage.
This significantly reduces opportunities for malicious actors to exploit checked baggage for unlawful purposes.
Establishing Positive Passenger Bag Match
The Recommended Practice formalizes the industry principle of Positive Passenger Bag Match (PPBM).
Every checked bag should correspond to:
- a ticketed passenger;
- a valid baggage record;
- a confirmed boarding status.
If the passenger does not board, the baggage must be identified immediately so that appropriate security action can be taken.
Supporting Automated Reconciliation
RP 1739 encourages airlines to implement integrated Departure Control Systems and Baggage Reconciliation Systems that automate the matching process.
Automation enables airlines to reconcile thousands of checked bags accurately while reducing manual workload and minimizing operational errors.
Improving Baggage Accountability
Passenger/Baggage Reconciliation also strengthens baggage accountability.
Every baggage record remains linked to:
- passenger identity;
- boarding status;
- baggage License Plate Number;
- baggage loading status.
These relationships improve baggage tracing, baggage security, operational reporting, and post-flight investigation.
Promoting Global Consistency
Ultimately, RP 1739 exists to ensure that airlines throughout the world apply consistent Passenger/Baggage Reconciliation procedures regardless of airport, aircraft type, or operating carrier.
By standardizing reconciliation terminology, workflows, baggage status definitions, and operational responsibilities, the Recommended Practice supports safer, more secure, and more interoperable baggage operations across the global aviation industry.
Operational Importance
RP 1739 is one of the aviation industry’s most important security standards because it establishes the operational procedures that ensure every checked bag is positively matched with its passenger before aircraft departure. Although baggage screening technologies have advanced significantly, Passenger/Baggage Reconciliation remains a critical layer of aviation security by ensuring that airlines know precisely which passenger is associated with every checked bag loaded onto an aircraft.
The Recommended Practice transforms passenger boarding and baggage loading into one integrated process. Rather than treating passenger check-in and baggage handling as separate activities, RP 1739 requires airlines to reconcile passenger boarding status with baggage loading records before departure. This integration greatly improves security while strengthening operational accountability throughout the baggage journey.
Preventing Unaccompanied Baggage
The principal operational objective of RP 1739 is preventing baggage from travelling without its owner unless appropriate security procedures have been completed.
If a passenger fails to board:
- the associated baggage is immediately identified;
- baggage loading is prevented or interrupted;
- baggage handlers locate the affected baggage;
- the baggage is removed or re-screened before any subsequent flight.
This process significantly reduces the opportunity for prohibited items or explosive devices to be transported through intentionally abandoned baggage.
Integrating Passenger and Baggage Operations
Passenger/Baggage Reconciliation links two operational systems that historically operated independently:
- passenger processing;
- baggage processing.
Passenger boarding status maintained by the Departure Control System (DCS) becomes directly associated with baggage identification maintained by the Baggage Reconciliation System (BRS).
Only when both systems confirm a positive match is baggage authorized for transport.
Improving Baggage Accountability
Every checked bag receives:
- a unique License Plate Number (LPN);
- a passenger association;
- boarding status;
- loading status;
- reconciliation status.
This complete chain of accountability enables airlines to determine exactly where baggage was accepted, loaded, transferred, or removed during the baggage journey.
Operational investigations therefore become considerably more accurate.
Supporting Aviation Security
Passenger/Baggage Reconciliation complements rather than replaces baggage screening.
Security screening identifies dangerous articles.
Passenger/Baggage Reconciliation ensures that baggage remains associated with its owner.
Together these two processes create multiple independent security layers protecting commercial aviation.
Supporting Operational Recovery
Reconciliation systems also improve operational recovery.
When baggage fails to travel with its passenger, reconciliation records immediately identify whether the baggage:
- remained at origin;
- was intentionally offloaded;
- became delayed;
- travelled separately.
This information supports baggage tracing while reducing passenger uncertainty.
Technical Structure
RP 1739 establishes a structured operational framework connecting passenger processing, baggage processing, security screening, and baggage handling.
Its principal technical components include:
- Departure Control System (DCS);
- Baggage Reconciliation System (BRS);
- baggage identification;
- reconciliation status;
- baggage messaging;
- security procedures;
- operational documentation.
Together these systems maintain positive baggage matching throughout the departure process.
Departure Control System (DCS)
The Departure Control System manages passenger information.
Typical DCS responsibilities include:
- passenger check-in;
- seat assignment;
- boarding pass issuance;
- passenger boarding status;
- passenger manifest creation.
Throughout reconciliation, the DCS provides the authoritative record indicating whether each passenger has boarded the aircraft.
Baggage Reconciliation System (BRS)
The Baggage Reconciliation System manages baggage information.
Its primary functions include:
- recording baggage tag numbers;
- recording License Plate Numbers;
- monitoring baggage scans;
- confirming baggage loading;
- comparing baggage records against boarded passengers.
The BRS continuously exchanges information with the Departure Control System to determine whether every loaded bag has a corresponding boarded passenger.
Passenger–Baggage Association
During check-in, every checked bag is electronically linked to its passenger.
The association includes:
- passenger name;
- reservation record;
- baggage tag number;
- License Plate Number;
- destination;
- flight information.
This association remains active until baggage reaches its final destination.
Baggage Status Categories
RP 1739 defines several operational baggage reconciliation statuses.
Reconciled Baggage
A reconciled bag is one whose passenger has boarded and whose baggage has been confirmed as loaded.
This represents the normal operating condition.
The baggage is authorized to travel.
Not Seen (UNAR)
A Not Seen bag refers to baggage whose passenger boarded successfully but whose baggage was not confirmed as loaded.
Typical causes include:
- baggage transfer delay;
- missed baggage scan;
- baggage handling delay;
- baggage routing issue.
The baggage is normally withheld from loading and forwarded on a subsequent flight after appropriate security procedures have been completed.
Unaccompanied Baggage
An Unaccompanied bag belongs to a passenger who did not board the aircraft.
Under RP 1739:
- the baggage must not travel on that flight;
- it must be removed or withheld;
- it may only travel later following the appropriate security controls.
Each unaccompanied bag must be clearly identified within operational systems.
Reconciliation Status Table
| Baggage Status | Passenger Status | Operational Action |
|---|---|---|
| Reconciled | Passenger boarded | Baggage loaded and transported normally |
| Not Seen (UNAR) | Passenger boarded | Baggage not confirmed as loaded; hold and forward on a later flight after required processing |
| Unaccompanied | Passenger did not board | Baggage removed or subjected to appropriate security screening before any later carriage |
This standardized status model enables airlines worldwide to apply consistent reconciliation procedures.
Operational Messaging
Passenger/Baggage Reconciliation depends upon continuous electronic messaging between airline systems.
Operational information includes:
- baggage source information;
- baggage loading confirmation;
- passenger boarding status;
- baggage reconciliation status;
- baggage transfer updates.
These exchanges support real-time decision-making before aircraft departure.
Automated Decision Support
Modern BRS platforms automatically compare:
- passenger boarding lists;
- baggage loading records;
- baggage scans;
- aircraft loading status.
If discrepancies occur, alerts are generated immediately.
This automation significantly reduces manual workload while improving reconciliation accuracy.

Implementation Guidelines
Successful implementation of RP 1739 requires coordinated procedures involving airlines, airports, ground handlers, and aviation security organizations.
Airline Responsibilities
Participating airlines should:
- associate every checked bag with a passenger;
- maintain accurate passenger boarding records;
- implement Departure Control System integration;
- operate a Baggage Reconciliation System;
- remove or re-screen no-show baggage;
- document reconciliation outcomes.
Departure Control Responsibilities
Departure Control personnel are responsible for:
- maintaining the passenger boarding list;
- identifying no-show passengers;
- communicating boarding status to the BRS;
- supporting aircraft departure clearance.
Baggage Handling Responsibilities
Ground handling personnel should:
- scan baggage throughout processing;
- verify baggage loading;
- remove no-show baggage;
- identify delayed baggage;
- update baggage reconciliation records.
Security Responsibilities
Airport security organizations ensure that:
- unaccompanied baggage receives appropriate security controls;
- re-screened baggage complies with applicable regulations;
- baggage removal procedures satisfy national aviation security requirements.
Documentation Requirements
Operational records should include:
- passenger boarding status;
- baggage License Plate Numbers;
- reconciliation reports;
- offload documentation;
- security screening records;
- baggage forwarding information.
These records provide a complete audit trail supporting operational investigations and regulatory compliance.
Operational Workflow
A typical RP 1739 reconciliation process follows these steps:
- The passenger checks in and the checked baggage is tagged with a License Plate Number.
- The Departure Control System records the passenger’s itinerary and baggage association.
- The Baggage Reconciliation System records the baggage tag and monitors baggage movement.
- The baggage is screened and enters the baggage handling system.
- Boarding agents scan passengers as they board the aircraft.
- The Departure Control System updates passenger boarding status.
- The Baggage Reconciliation System compares boarded passengers with loaded baggage.
- Any unmatched baggage generates an automated reconciliation alert.
- Ground handlers locate and remove the affected baggage or apply the required security procedures before any later flight.
- Once every loaded bag has been reconciled with a boarded passenger—or has been appropriately identified and handled as unaccompanied baggage—the aircraft is cleared for departure.
System Integration
RP 1739 depends upon close integration with numerous airline operational systems.
Departure Control Systems (DCS)
The DCS maintains passenger boarding status and provides the authoritative passenger data required for reconciliation.
Baggage Reconciliation Systems (BRS)
The BRS records baggage identification, baggage scans, reconciliation status, and loading confirmation while automatically identifying discrepancies.
Resolution 740 — Baggage Tags
Standardized baggage tags provide the physical identification linking checked baggage to passenger records.
Resolution 751 — Use of the 10-Digit License Plate
The ten-digit License Plate Number uniquely identifies every checked bag throughout the reconciliation process.
Resolution 753 — Baggage Tracking
Custody events recorded under Resolution 753 complement reconciliation by documenting baggage movement from check-in through aircraft loading and arrival.
RP 1745 — Baggage Messaging
Standardized baggage messages exchange baggage status, source information, and reconciliation updates between airline systems and interline partners.
Resolution 780 — Interline Traffic Agreement
Passenger/Baggage Reconciliation continues across interline itineraries, ensuring that baggage transferred between participating airlines remains associated with the correct passenger and complies with agreed operational and security procedures.
ICAO Annex 17 and Airport Security Systems
RP 1739 provides the operational implementation of ICAO Annex 17 security principles by integrating passenger boarding verification, baggage reconciliation, and security screening into one coordinated departure process.
Benefits for Airlines
RP 1739 provides airlines with one of the aviation industry’s most effective operational security controls by ensuring that every checked bag can be positively associated with a boarded passenger or handled under approved security procedures. Although originally introduced for aviation security, the Recommended Practice also improves baggage accountability, operational efficiency, and customer service.
Enhanced Aviation Security
The principal benefit of Passenger/Baggage Reconciliation is the prevention of unauthorized or suspicious baggage travelling without its passenger.
By electronically comparing passenger boarding status with baggage loading status, airlines can identify discrepancies before aircraft departure and take immediate corrective action.
This layered approach complements baggage screening technologies and forms an essential component of airline security programmes.
Improved Operational Control
Passenger/Baggage Reconciliation provides airlines with real-time visibility of baggage status throughout the departure process.
Operational control personnel can immediately determine whether baggage is:
- reconciled;
- awaiting loading;
- delayed;
- transferred;
- unaccompanied;
- removed from the aircraft.
This improves decision-making while reducing uncertainty during aircraft turnaround.
Reduced Mishandled Baggage
Because every checked bag is electronically associated with its passenger and continuously monitored throughout departure, baggage handling errors are identified earlier.
Benefits include:
- fewer loading errors;
- fewer baggage omissions;
- improved baggage transfer accuracy;
- better baggage recovery following disruptions.
These improvements contribute directly to lower mishandled baggage rates.
Better Passenger Confidence
Passengers increasingly expect airlines to maintain high standards of baggage security.
Passenger/Baggage Reconciliation reassures travellers that baggage handling follows internationally recognized security procedures while maintaining accurate baggage tracking throughout the journey.
Benefits for Airports
Airport operators also benefit significantly from standardized reconciliation procedures.
Improved Security Coordination
Passenger/Baggage Reconciliation integrates:
- airline operations;
- airport security;
- baggage handling;
- aircraft loading.
This coordinated approach improves communication between operational organizations while supporting airport security objectives.
Faster Aircraft Turnaround
Modern Baggage Reconciliation Systems automatically identify reconciliation discrepancies before departure.
Ground handling personnel can therefore locate affected baggage more quickly, reducing departure delays associated with manual baggage searches.
Enhanced Operational Visibility
Airport operations centres receive real-time information concerning:
- baggage loading;
- passenger boarding;
- reconciliation status;
- baggage removal activities.
This operational visibility improves overall departure management.
Benefits for Ground Handlers
Ground handling organizations play a central role in implementing RP 1739.
Standardized Loading Procedures
Ground handlers receive clear instructions concerning:
- baggage loading;
- baggage reconciliation;
- baggage removal;
- baggage transfer.
This reduces ambiguity during aircraft loading while improving consistency across different airlines.
Reduced Manual Searching
Modern reconciliation systems identify precisely which baggage requires removal.
Instead of manually searching entire aircraft holds, baggage personnel receive the exact License Plate Number and loading position of the affected baggage.
This significantly reduces aircraft turnaround delays.
Improved Baggage Traceability
Every baggage movement is recorded electronically.
Ground handlers therefore gain improved visibility regarding:
- baggage location;
- loading sequence;
- transfer status;
- offloaded baggage.
This information supports faster baggage recovery during irregular operations.
Auditability and Compliance
RP 1739 creates one of the most comprehensive audit trails within airline baggage operations.
Complete Passenger–Baggage Records
Every reconciliation transaction documents:
- passenger identity;
- boarding status;
- baggage License Plate Number;
- baggage loading status;
- reconciliation outcome;
- baggage removal, where applicable.
These records provide complete operational accountability throughout the departure process.
Operational Note
Passenger/Baggage Reconciliation is both a security process and an operational control process. Every reconciliation decision should be supported by documented electronic records generated by the Departure Control System (DCS), Baggage Reconciliation System (BRS), and associated baggage messaging platforms to demonstrate compliance with airline procedures and applicable aviation security regulations.
Regulatory Compliance
Passenger/Baggage Reconciliation supports compliance with:
- ICAO Annex 17;
- national civil aviation security regulations;
- airline security programmes;
- airport operating procedures.
Because reconciliation records are retained electronically, airlines can demonstrate compliance during regulatory inspections and security audits.
Incident Investigation
Should an operational or security incident occur, reconciliation records enable investigators to determine:
- whether the passenger boarded;
- whether baggage was loaded;
- whether baggage was removed;
- when reconciliation decisions were made;
- who authorized operational actions.
This strengthens post-event analysis and supports continual improvement.
Relationship to Other IATA Standards
RP 1739 is closely integrated with numerous IATA baggage and passenger service standards.
| Standard | Relationship to RP 1739 |
|---|---|
| Resolution 740 – Baggage Tags | Passenger/Baggage Reconciliation depends upon standardized baggage tags to identify checked baggage accurately. |
| Resolution 751 – Use of the 10-Digit License Plate | The License Plate Number uniquely identifies every checked bag throughout the reconciliation process. |
| Resolution 753 – Baggage Tracking | Resolution 753 records baggage custody changes, while RP 1739 determines whether baggage is authorized to travel with its passenger. |
| RP 1745 – Baggage Messaging | Standardized baggage messages communicate reconciliation status, baggage source information, and baggage movement between airline systems. |
| Resolution 780 – Interline Traffic Agreement | Interline baggage remains subject to Passenger/Baggage Reconciliation procedures when transferred between participating airlines. |
| Resolution 792 – Bar-Coded Boarding Pass | Boarding-pass information supports automated reconciliation by linking passenger boarding events with baggage records. |
| ICAO Annex 17 – Security | RP 1739 provides practical operational guidance supporting ICAO requirements concerning Positive Passenger Bag Match and the handling of unaccompanied baggage. |
Together, these standards establish a comprehensive framework for secure, traceable, and interoperable baggage operations.
Real-World Use Cases
International Departure
A passenger checks in for an international flight and checks one suitcase.
During boarding, the passenger fails to appear at the departure gate.
The Baggage Reconciliation System immediately identifies the associated License Plate Number.
Ground handling personnel locate and remove the baggage before aircraft departure in accordance with RP 1739.
Interline Connection
A passenger travelling on two airlines misses a connecting flight because of weather disruption.
The passenger’s baggage arrives at the transfer airport.
The reconciliation system identifies the baggage as temporarily unaccompanied.
The baggage is held and transferred to the passenger’s rebooked flight after appropriate security procedures have been completed.
Aircraft Loading
While loading baggage, one suitcase fails to scan successfully.
The BRS records the baggage as Not Seen (UNAR).
Ground handlers locate the baggage in the baggage make-up area and complete the required scan before authorizing loading.
Automated Airport
A major hub airport operates a fully integrated Departure Control System, Baggage Reconciliation System, and RFID baggage tracking platform.
As passengers board, reconciliation occurs automatically.
Aircraft loading cannot be finalized until every loaded bag has been positively matched with a boarded passenger or processed under approved unaccompanied baggage procedures.
Last-Minute Passenger Cancellation
A passenger cancels after completing check-in.
The DCS updates the passenger status.
The BRS immediately identifies the checked baggage and generates an alert.
Ground handlers remove the baggage before departure, maintaining compliance with reconciliation requirements.
Security Alert
Airport security requests additional screening for baggage associated with a passenger selected for secondary security procedures.
Because baggage remains electronically linked to the passenger through the License Plate Number, the bag is rapidly identified and diverted for inspection before loading.
Industry Challenges
Although RP 1739 provides highly effective security procedures, implementation continues to present operational challenges.
Complex Airport Operations
Large hub airports process tens of thousands of bags daily.
Maintaining real-time reconciliation across multiple terminals, airlines, and aircraft requires sophisticated operational systems and reliable data exchange.
Legacy Technology
Some airlines continue operating older Departure Control Systems that provide limited integration with modern Baggage Reconciliation Systems.
System modernization remains necessary to achieve full automation.
Interline Coordination
Passenger/Baggage Reconciliation becomes more complex when passengers transfer between multiple airlines.
Participating carriers must exchange accurate baggage information and boarding status in real time to maintain continuous reconciliation.
Human Factors
Although reconciliation is increasingly automated, personnel remain responsible for:
- baggage removal;
- reconciliation verification;
- operational decision-making;
- security coordination.
Regular training remains essential to minimize operational errors.
Future Outlook
Passenger/Baggage Reconciliation will continue evolving alongside modern baggage technologies.
RFID-Enabled Reconciliation
RFID technology provides continuous baggage visibility throughout airport operations.
Future reconciliation systems will increasingly combine RFID tracking with passenger boarding information to improve reconciliation accuracy and reduce manual intervention.
Artificial Intelligence
Artificial intelligence may support:
- predictive baggage monitoring;
- automated reconciliation analysis;
- operational alert prioritization;
- disruption management;
- baggage recovery planning.
These capabilities will enhance operational efficiency while preserving the core principles of RP 1739.
Biometric Passenger Processing
As biometric boarding becomes more widespread, passenger boarding confirmation will occur automatically through facial recognition or digital identity verification.
This will strengthen the integration between passenger processing and baggage reconciliation.
Fully Integrated Airport Operations
Future airport operational centres will combine:
- Departure Control Systems;
- Baggage Reconciliation Systems;
- baggage tracking;
- aircraft loading;
- airport security;
- passenger processing.
Within these integrated environments, reconciliation will become an increasingly automated component of real-time airport operations while continuing to uphold the principle of Positive Passenger Bag Match.
Amendment Status
RP 1739 remains an active Recommended Practice within the IATA Passenger Services Conference framework and continues to provide internationally recognized guidance for Passenger/Baggage Reconciliation procedures. While the core principle of Positive Passenger Bag Match has remained consistent, implementation has evolved from manual reconciliation methods to highly automated processes integrated with Departure Control Systems, Baggage Reconciliation Systems, barcode scanning, RFID technology, and real-time baggage messaging. The Recommended Practice continues to align with ICAO Annex 17 security requirements and reflects ongoing technological advancements in baggage management.
