Interline agreements are contractual agreements between two or more airlines that allow them to sell connecting flights on each other`s airlines under a single booking. The International Air Transport Association (IATA) facilitates these agreements, which allow airlines to expand their networks and provide more options to their customers.
Under an interline agreement, airlines agree to transport passengers and baggage between two or more points using a combination of flights on their own airlines and on their partner airlines. This means that passengers can purchase a single ticket and check their baggage through to their final destination, even if they are flying on multiple airlines.
Interline agreements are essential for smaller airlines that do not have a global reach. By partnering with larger airlines, they can offer their customers more destinations and connections, without having to invest in new aircraft or routes. For the larger airlines, interline agreements allow them to expand their networks without having to enter into expensive mergers or acquisitions.
Interline agreements can be beneficial for customers, who can benefit from reduced travel times, more convenient connections, and a wider range of options for their travel plans. For example, a passenger traveling from New York to Sydney may be able to purchase a single ticket that includes a flight on American Airlines from New York to Los Angeles, followed by a connection on Qantas Airways from Los Angeles to Sydney.
The process of booking an interline flight can be complex, as it involves multiple airlines, ticketing systems, and baggage policies. However, customers can usually purchase interline tickets through a travel agent or the airlines` websites.
Interline agreements are subject to regulatory approval in many countries, and there may be restrictions on which airlines can enter into these agreements. However, they are an important tool for airlines to expand their networks and provide more options to their customers.
In conclusion, interline agreements are an essential component of the airline industry, allowing airlines to expand their networks and provide more options to their customers. With the support of IATA, these agreements have become a standard practice in the aviation industry, benefiting airlines and passengers alike.
