Hook

Why and how can an airline sell more tickets than it has seats? It's called overbooking, and with holiday travel coming, it's worth knowing how it works.

Noshow

Airlines know some passengers won't show up. People miss connections, change plans or skip flights. And an empty seat earns nothing once the plane takes off.

Math

So airlines use past data to predict how many people will no show, and they sell a few extra tickets to fill those seats.

Legal

In the United States, overbooking is legal. But when too many people show up, the airline has to ask for volunteers first.

Volunteer

Volunteers usually get offers like travel credits or cash to take a later flight.

Bumped

If there aren't enough volunteers, someone can be bumped. Bumped passengers are often owed cash compensation, up to four times the one way fare depending on the delay, with a cap.

Who

Who gets bumped? Airlines can consider things like check in time, the fare you paid and frequent flyer status. So checking in early helps.
