How do airlines decide who gets bumped from flights when they overbook? Airlines use a priority list. The specifics do vary by airline, but factors that are commonly used include: The status of the passenger in the airline's frequent-flyer program.

When a flight is oversold and there are no volunteers, airlines in 2026 follow a strict "Boarding Priority" hierarchy to determine involuntary denied boarding. While specific policies vary by carrier, the general order of protection starts with passengers with disabilities and unaccompanied minors, followed by those with high-tier frequent flyer status and passengers in premium cabins (First/Business). After these groups, airlines typically bump passengers based on check-in time (the "last to check in, first to be bumped" rule) or the fare class paid (those on the cheapest "Basic Economy" tickets are at higher risk). In 2026, new DOT regulations require airlines to provide a written statement of rights and immediate compensation—up to 400% of the one-way fare (capped at approximately $2,150)—to anyone bumped involuntarily. Bumping after boarding is now strictly prohibited unless for safety or security reasons.
