Until now, only major network operators such as United Airlines and Lufthansa had electronic ticket interconnection agreements, but IATA`s mandate to remove paper tickets at the end of 2007 changed this situation by requiring smaller airlines to introduce electronic tickets. Interline chords are turning points. For example, American Airlines may be able to issue the ticket on an American United route, but United may not be able to issue on the same route. A single interline agreement is called a one-sided interline. Airlines may also agree to a bilateral interline agreement in which each airline can issue the ticket to the other carrier. Interline agreements differ from code-sharing agreements in that codeshare agreements generally relate to the numbering of a flight with the company`s code (acronym), although the flight is operated by another airline. However, codeshare relationships may affect whether an interline ticket (or e-ticket) can be issued, since the codeshare marketing carrier and code-sharing operator must have interline agreements with all other airlines in the itinerary for a single ticket to be issued. Smaller airlines have generally entered into interline agreements with large network operators moving to their markets. Most new low-cost companies, which sell only directly to consumers (and not through global agencies or distribution systems), do not support the interline at all. Signatory airlines may vote at Propere meetings. Non-signatories may attend meetings, but cannot vote. If you cannot vote, this can have a negative impact on your interline performance, as decisions are made at adjacent meetings.
Revenues generated by routes that consist of a segment transport (shared code segment or otherwise) carried out by an airline connecting to a flight (codeshare or otherwise) operated by the other airline (these routes are referred to as “transit flights”) are distributed among the airlines, in accordance with a specific rate agreement. , a copy of this copy in Appendix A (the “special agreement”). The special agreement is amended by mutual agreement between the airlines, so that it is no less favourable to the non-operating airline on the current origin and destination routes than the most favourable agreement offered by the competent airline to another non-operating airline for similar origin and destination routes.
