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. These agreements facilitate cooperation between airlines with respect to 3 The number of multilateral/bilateral agreements involving debtors makes it very difficult to identify each of these agreements, but debtors strive to facilitate all interline agreements, whether or not a particular agreement is art. A. is mentioned. 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. Airlines benefit from higher turnover. Both airlines can offer a very competitive common fare, which attracts customers to their respective routes. Long-haul airlines add additional passengers to their flights. Cash flow also benefits the airline issuing the ticket, as ticket revenues for both airlines are recovered by the issuing airline. Internal accounting procedures process the notes through branch agreements, and the issuing airline then pays other airlines to travel on their routes on the basis of the Interline Prorate agreement. The agreement also simplifies customer requests due to baggage irregularities and provides an internal claims settlement system after the final customer count.
Most online travel agencies only indicate itineraries that can be booked on one of their reservation systems. However, Orbitz sometimes displays inviolable interline routes. Examples have been found so far on routes to Mexico, which involve the absence of Aero California, or can currently be found on routes to Indonesia with Lion Air. These are displayed on Orbitz as a “contact airline to buy.” 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. An Interline agreement, also known as interlining, Interline Billeting or Interline-Reservation, is an agreement between two or more airlines to treat passengers when their itinerary involves travel with several airlines. This means that they undertake to ship their luggage to their final destination and check them in for their destination. A codeshare flight is different from an Interline flight, because a codeshare flight is the entire flight, while an interline is a flight within a larger route.
