Airline Cancellation Policies

Flight cancellation policies vary by airline and circumstance. When an airline cancels a flight, most will try to rebook passengers on the next available flight.

Airlines are not required to reimburse travelers for losses incurred as a result of a canceled flight. These losses may include such as a prepaid, non-refundable:

Hotel room

All-inclusive vacation or resort

A cruise

A tour or safari

Concert or entertainment tickets

Travelers concerned about protecting any non-refundable, pre-paid trip expenses should buy travel insurance.
