The IATA Multilateral Interline Traffic Agreements (MITA) is an agreement under which passengers and freight use a standard transport document (i.e. passenger ticket or air travel letter) to travel on different modes of transport participating in a route to reach a final destination. The interline, also known as interline and interline ticketing, is a voluntary commercial agreement between different airlines to treat passengers travelling on routes requiring several flights with several airlines.  Such agreements allow passengers to switch from one flight with one airline to another airline flight without having to pick up their baggage or re-register it. Airlines can also promise a free booking change if the service is interrupted due to a delay. Dohop therefore does most of the most of the project and is very easy on the IT resources of the airlines. Due to the weak pricing structure, Dohop`s interline programs are an important profit centre for its customers. Dohop`s Interline solution has the advantage of being highly customizable with its rooted start-up DNA, allowing for greater flexibility in pricing and relationships with each airline on a case-by-case basis. For them, issuing an interline ticket using the traditional interline process has several additional cost elements that may not fit their business model. A high-level look at some of the cost makers associated with issuing a conventional interline ticket shows several items such as GDS distribution fees, IATA agency commissions and volume incentives for key partners to secure market share. More importantly, this will bridge the gap between these two different business models by providing them with a mechanism to connect and benefit from the other party`s networks. 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.
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.
