Flight disruptions are seen as increasingly unsymusely by both air passengers and airlines, particularly given the widespread use of electronic tickets or electronic tickets. The production of an FIM requires that the e-ticket be converted into a normal paper ticket and that the data be sent manually to the receiving airline. Several airlines announced in 2000 that they would work together to smooth and digitize these transactions.  I think people should know that there are many, many underlying interline agreements. Many date back to the 1960s and 1970s, long before alliances. Interline agreements cover many, many different services. Pocket control and rehousing are just the ones most flyers are aware of. For example, some airlines take over the original airline free of charge. Yes, that is always the case. What I get is that a lot of airlines work together behind the scenes, as dashing as the aviation industry. While alliances with normal daily functioning have a lot of weight, in irropable, especially internationally, everything can be thrown out the window. But what is even more surprising is that airlines that normally do not have connections, make exceptions and issue tickets, buy tickets to bring passengers to their destination. But don`t expect this to happen if your ticket was on an error fee, etc.
All airlines take erroneous airline tickets like poison when they are hit. What happens next is usually that the issuing airline rejects the value of this FIM, conducts research and is credited with the amount of the original flight voucher. A FIM is usually issued at a door, ticket office or transit counter by an airline agent and notes its original line and ticket numbers as well as those of the new route, making the FIM a new ticket. A FIM is only valid for a specific flight with a new airline that is not the airline for which the ticket was originally issued. For example, a delta-Gate agent could create an FIM for a flight with United and send the data to United. The FIM would then be accepted as a regular ticket on the United flight indicated. I often saw a fare base, printed on the newly issued ticket, when it was reissued, and I wondered if that fare was what the airlines were paying each other. Jet Airways passengers are at risk of further suffering if their flights with full-service airlines such as Air India and Vistara are cancelled after entering into cordial agreements with the indebted airline. This allows Jet Airways to book its passengers on a Vistara flight at a predetermined price. However, according to a business source, the agreement was cancelled “partly for non-payment of taxes.” The source also said that the agreement was no longer viable because of the grounding of the aircraft.
