Don`t confuse ticketing interline agreements with code-sharing or operator companies: as a rule, U.S. airlines that do not have a partnership with each other also have an interline agreement. A few years ago Delta decided to disable an interline agreement with American, I think because they found that American more passengers on them during irregular operations than vice versa. Airlines participating in airline alliances such as Star Alliance, SkyTeam or oneworld almost always have interline agreements. But direct competitors can also benefit from Interline agreements. While this gives the biggest types of agreements, it seems that they have been much emphasized lately. If two airlines have an interline agreement, they usually take care of check-in and baggage for passengers on the other side. This means that travellers must check in only once for all flights on the itinerary and that their luggage will be delivered from the first airline to the second, without having to pick them up and hand them over manually. Let us briefly move on to these four types of agreements: there is currently no airline that allows smoking on their planes, whether or not they are part of a code-sharing code. Only the issuing carrier is responsible for the payment of the commission to the Agency. The amount of the commission is determined according to the total price of the ticket, but the percentage depends on the amount paid if only one airline is involved. When a ticket is issued for an Interline itinerary, one of the airlines on that route is chosen by the ticket provider as the transmitting airline, commonly known as the Plating Carrier. The coating provider collects the entire tariff from the customer, either through its own distribution channels (e.g.B.
website or ticketing office), or through travel agencies. Travel agencies transfer fares and taxes collected through The De Reporting Corporation (ARC) to the airline in the United States or the billing and billing plan (BSP) to the rest of the world. The airline that actually carried the passenger (the exporting airline) sends an invoice to the airline that issues and places, usually through the IATA clearing house, to recover its share of the ticket price and taxes. The airline linked to the operation is responsible for the transfer of passenger taxes to the various governments and airports. Some taxes are based on sales (U.S. taxes) and are transferred by the issuing airline. 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. Closer partnerships include more exchanges, cooperation and more strategic measures between the airlines involved. These include code-sharing and joint ventures. Code sharing is seen as the next step up interlining and sees how airlines collaborate by placing their „codes” on other people`s flights. What is this code? It depends on the airline. IATA gives the codes to all member airlines, and that is what is shown on the flight number of each flight.
