The IATA Resolution 753 implementation guide (attached Joint IATA-A4A Baggage Tracking Implementation Guide_February 2017.pdf) defines the tracking points shown below. To support this the following time elements have been defined:
| Element | Where | Definition |
|---|---|---|
| BACIT | 1 | The "Bag Actual Checked In Time" is the DateTimeUTC when the bag was checked and delivered to the baggage handling system. This corresponds to the BagEventCode "BagChecked". This should occur when it is impossible for the passenger to decide not to check the baggage after all. It is however possible for the bag to be rejected for technical reasons (too long). Always UTC. |
| BTBBT | Between 3 and 5 | The "Bag To BHS BinTime" is the DateTimeUTC when the baggage handling system actually delivered the bag for further handling. This will typically be, for baggage handling systems with sorting, when the bag is placed in a bin. This corresponds to the BagEventCode "BagToBhsBin". Always UTC. An estimate of this timestamp is defined by BEBFT. |
| BEBFT | Between 3 and 5 | The Bag Estimated BHS Finish Time is the DateTimeUTC when the baggage handling system estimates that the bag will be finished and ready for further handling. This will typically be, for baggage handling systems with sorting, when the bag is placed in a bin. This is an estimate for the BagEventCode "BagToBhsBin". Always UTC. |
| BLOAT | 7 | The "Bag Loaded Time" is the DateTimeUTC for the last BagLoaded event. The timestamp can indicate when the bag was loaded into a container, or when it was loaded onto an aircraft. This corresponds to the last BagEventCode "BagLoaded". Always UTC. |
| BUNLT | 8 | The "Bag Unloaded From Aircraft Time" is the DateTimeUTC when the bag was unloaded from the aircraft. This corresponds to the BagEventCode "BagUnloaded". Always UTC. |
| BAOBT | 11 | The Bag Actual On Belt Time is the DateTimeUTC when the bag actually is placed on the baggage belt/carousel and soon will be ready for pick up by the passenger. This corresponds to the BagEventCode "BagOnBelt". Always UTC. |
| BTOTT | Between 9 and 10 | The "Bag To Transfer Time" is the DateTimeUTC when the bag is delivered to transfer processing. This corresponds to the BagEventCode "BagToTransfer". Always UTC. |
| BETPT | 12 | The Bag Estimate To Passenger Time is the DateTimeUTC when the bag is estimated to be ready to be picked up by the passenger. This is an estimate for the BagEventCode "BagToPassenger". Always UTC. |
| BTPAT | 12 | The "Bag To Passenger Time" is the DateTimeUTC when the bag is made directly available to the passenger. This corresponds to the BagEventCode "BagToPassenger". Always UTC. An estimate of this timestamp is defined by BTPATE. |
