The ITA table is checked when the TTP/ET/TKT 2 input is used. To verify the interline agreement between two airlines, please indicate: TGAD-YY/ZZ (YY being the valid airline and ZZ the second airline). The Interline Ticketing Agreement (ITA) refers to the list of airlines that have an existing ticketing agreement with other airlines. Important: airline agreements should not be reciprocal. The interline ticketing agreement should not be confused with code-sharing companies or operators: the interline is when flights are mixed from different flight codes in the PNR line. In this case, the ITA table is checked. In code-sharing and operational carrier situations, flight segments have the same code as the validating carrier, but are 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. 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. If there is a problem, always check for flights in the itinerary that are made by another company (codeshare). View Interline ticketing agreements from a valid airline or between two airlines with a TGAD entry. 1. To view this table, enter: TGAD-YY (where YY is the airline`s double-digit validation code) The example above means that 7X flights can be booked on plate 6X. Note: If there is no code sharing, resolution 852 is violated if the ticket is issued under the LH mark.
