An interline agreement is a contract between two airlines to accept each other’s tickets, transfer baggage and rebook passengers during disruption.
Also called: Interlining.
How it works#
Without one, an airline cannot move a passenger onto another carrier even when seats are empty, which is precisely why some rebookings fail during disruption. The agreement also underpins through-checked baggage and tickets that combine several airlines on one document. Low-cost carriers generally hold no interline agreements at all.
Not to be confused with#
An interline agreement is not the same as a codeshare: interlining governs technical acceptance of tickets, a codeshare governs selling under another airline’s flight number.

- Codeshare: A codeshare is a flight sold by one airline under its own flight number while a different airline actually operates it.
- Through-checked baggage: Through-checked baggage is luggage tagged to the final destination at the first departure, so it does not need collecting at the connecting airport.
- Rebooking on another airline: Rebooking on another airline is transferring a ticket to a different carrier so the passenger reaches the destination sooner after disruption.
