As the aviation industry continues to evolve, it is important to understand the differences between different agreements that airlines enter into. Two common agreements are interline agreements and codeshare agreements. While they may seem similar, there are key differences between the two.

Interline agreements are agreements between two or more airlines that allow passengers to travel on multiple airlines with a single ticket and a single check-in. This means that if one leg of the journey is delayed, the passenger can still make their connecting flight on another airline. Interline agreements also allow airlines to share baggage handling and ticketing systems, making the travel experience more seamless for passengers.

On the other hand, codeshare agreements are agreements between two airlines where one airline puts its code (flight number) on the flights of another airline. This allows passengers to book and travel on a flight operated by one airline but marketed by another. Codeshare agreements often enable airlines to expand their network and offer more flights to passengers.

One key difference between the two agreements is ownership and control of the flights. With interline agreements, each airline operates its own flights, while with codeshare agreements, one airline operates the flight, but the other airline markets it as its own.

Another difference is revenue sharing. With interline agreements, each airline receives revenue for its own flights, while with codeshare agreements, the airline operating the flight receives revenue for the flight, and the marketing airline receives a portion of that revenue.

Finally, interline agreements tend to be more beneficial for passengers in terms of flexibility, as they allow passengers to make changes to their itinerary more easily. Codeshare agreements, on the other hand, can be more beneficial in terms of pricing, as airlines can offer more competitive pricing by pooling resources.

In summary, while both interline and codeshare agreements allow airlines to offer more options to passengers, there are significant differences between the two. Interline agreements allow passengers to travel on multiple airlines with a single ticket, while codeshare agreements allow airlines to expand their network by marketing flights operated by other airlines. Understanding these differences can help passengers make informed decisions when booking their travel.
