A codeshare agreement is the next step in cooperation between airlines. This is when two airlines realize that there is value in cooperation, and they decide that they want to place their “codes” on each other`s flights. As a general rule, the main advantage is that it allows airlines to partner in a codeshare agreement. Thank you, it was a very useful contribution! Speaking of joint ventures, here is the most recent that has happened: www.reuters.com/article/us-air-france-vietnam-airlines/air-france-continues-long-haul-drive-with-vietnam-airlines-joint-venture-idUSKBN1CF16M Like network operators, some low-cost Asian airlines are finding through partnerships a solution to develop their network and strengthen their position in the tense Asian market. The strategic alliance model, previously limited to regular airlines, has recently been adopted by low-cost airlines, as evidenced by the creation of U-Fly and Value Alliance in February and May 2016. For example, Alaska and Qantas` partners both allow them to collect and redeem miles on each other`s flights through their own programs, even though Qantas is a oneworld member and Alaska is not part of an alliance. This partnership also extends to Qantas, which allows some members of Alaska`s elite to access their lounges and Alaska is able to sell Qantas flight revenues on the AS website. Interline agreements are the most basic types of agreements you can have between airlines. An Interline agreement is simply a commercial agreement between airlines to treat passengers when travelling with several airlines on the same route.
This allows passengers to check their luggage to their final destination, check their location to their destination, possibly be re-routed to another airline in case of irregular operation, etc. In 1967, Richard A. Henson joined the country`s first codeshare relationship with US Airways` predecessor, Allegheny Airlines.  The term “codeshare” was coined by Qantas and American Airlines in 1989 and in 1990, the two companies made available their first codeshare flights between a number of Australian and American cities. Since then, the sharing of parts of codes has spread in the aviation sector, particularly as part of the formation of major airline alliances. These alliances have extensive code-sharing and network loyalty programs. As a general rule, even U.S. airlines that do not have a partnership with each other have an interconnection 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. We will briefly address these four types of agreements: under a codeshare agreement, the airline that manages the flight (the airline that holds the operating licenses, airport slots and flight planning/management and is responsible for ground handling services) is often referred to as an operating airline ope CXR, although the term IATA SSIM “Administrator Carrier” is more precise.
