In a codeshare agreement, two or more airlines share a flight. Codeshare flights have generally focused on aircraft planning and sharing. Because airlines generally depend on other partners to transport passengers to distant destinations where they are not heading, codeshare agreements serve as a logistical blessing. But don`t be afraid. In this manual, we talk about code sharing and interline agreements. First, let`s describe what they are exactly. Then you`ll find out how to determine if you`re on a code sharing or not. Finally, we`ll show you why you should take care of code sharing. Start.
Code sharing dates back to the 1960s. In 1967, Allegheny Airlines (USAir) entered into the first codeshare with a commuter airline in the United States. This practice became increasingly popular following the deregulating of the U.S. domestic market in the 1970s. Airlines also benefit from excellent code-sharing and interline service, from increased revenues to the development of successful partnerships. In addition, airlines can easily facilitate claims and invoices through a streamlined internal system through code-sharing and interconnection agreements. To illustrate this concept, we say that you are booked on a business class ticket with a stop in Europe. Even if the second leg of your ticket does not have a business class cabin, airlines can continue to sell a business class code. One of the best ways to earn miles with your favorite frequent flyer program is to give them as many paid flights as possible. For example, if you have decided to accumulate Japan Airlines miles in any way possible, you can earn miles on licensed codeshare flights.
Even if a route needs several airlines, I would still try to find the version with the underlying flight number as the codeshare variant (if they can rent it the same way). Whenever there are flight problems, code-sharing issues are the worst because airlines like to send you to the other side to fix them. 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. Conclusion: it can be confusing to recognize the difference between a codeshare flight and a normal flight. The best way to find out if you`re on a codeshare flight is to search a flight tracking site, like Flightstats. Moreover, a good but not infallible proxy to determine whether a flight is actually a codeshare is to compare the format of the flight number to that used on similar routes. It`s the same story for those with elite status. If you have United 1K Elite status and book a codeshare ticket on ANA marketed by United Airlines, your flight will continue to be insured by ANA. This means that you are not allowed to get upgrades, even if you have First Class United elite status.
Most major airlines today have codeshare partnerships with other airlines, and code sharing is an essential feature of major airline alliances. In general, code-sharing agreements are also part of trade agreements between airlines in the same alliances. Code and interline sharing agreements were invented to offer customers comfort and cost benefits.
