codeshares

Codeshare agreements are arrangements between airlines that allow them to operate a flight using another airline's flight number. This practice is common in the airline industry, particularly for flights that are operated by different airlines but serve the same route. The primary purpose of codeshare agreements is to increase the number of available seats on a route, thereby enhancing competition and potentially reducing fares for passengers.

In a codeshare agreement, one airline, known as the operating carrier, actually provides the aircraft and crew to operate the flight, while the other airline, known as the marketing carrier, sells the tickets and markets the flight. The operating carrier typically receives a fee for providing the aircraft and crew, while the marketing carrier may receive a commission on the ticket sales.

Codeshare agreements can be beneficial for both parties involved. For the operating carrier, it provides additional revenue and the opportunity to operate flights on routes where it may not have a direct presence. For the marketing carrier, it allows it to expand its route network without the need for additional aircraft or crew, and it can also benefit from the operating carrier's reputation and customer base.

However, codeshare agreements also have their challenges. Disputes can arise over the division of revenue, the marketing of the flight, and the handling of passengers. Additionally, if the operating carrier experiences delays or cancellations, it can negatively impact the marketing carrier's reputation and passenger satisfaction.

Overall, codeshare agreements are a common and important aspect of the airline industry, providing both opportunities and challenges for the airlines involved.
