The ITA table is checked when the TTP/ET/TKT input is used: company agreements must not be reciprocal. Don`t confuse interline ticketing agreements with codeshare or operating carriers: in code-sharing and operational carrier situations, flight segments have the same code as the airline that validates but is operated by other airlines. The ITA table is verified between the validating airline and the airline defined in DEI50. Note: DEI50 is an SSIM message that refers to comments posted in a Flight Information Entry (DO). 50 Duplicate Leg Cross Reference – Operation Leg Identification is the marketing carrier`s commentary indicating the operating flight number. If there is a problem, always check for flights in the itinerary that are made by another company (codeshare). 2. To verify the interline agreement between two airlines, please indicate: TGAD-YY/ZZ (where YY is the validating carrier and ZZ is the second largest airline). The Interline Ticketing Agreement (ITA) refers to the list of airlines that have an existing ticketing agreement with other airlines. View Interline ticketing agreements from a valid airline or between two airlines with a TGAD entry.
The interline is when flights are mixed from different airline codes in the PNR route. In this case, the ITA table is checked. Note: If there is no code sharing, resolution 852 is violated if the ticket is issued under the LH mark. 6X and YY have an electronic ITA, so an E-Ticket can be delivered on LH drive. However, flight 6X is operated by another airline (Other airline) and the 6X ticket is therefore refused. The example above means that 7X flights can be booked on plate 6X. 1. To view this table, enter: TGAD-YY (where YY is the airline`s double-digit validation code).
