Interline Agreement

Updated: 2017-03-27.

Interlining, also known as an interline agreement, is an agreement between two airlines that enables passengers to book multiple segments on multiple carriers to allow for a greater share of coverage by both airlines. Baggage is transferred through the interline connection to the final destination.

An interline agreement differs from a code share in that the operating carrier of each segment may not have the codeshare agreement which allows the other airline to sell tickets under their name. It also differs from a codeshare agreement in that only the operating carrier of each segment will distribute rewards to their respective frequent flier programs, though the ticket may have been booked through another airline.
