Airlines routinely sell more seats than the plane has. Usually everyone shows and it does not matter - but when a flight is oversold, someone gets bumped. Here is exactly what you are owed and how to claim it.
Part of our complete guide to airline customer service.
Quick answer: If the airline denies you boarding involuntarily on an oversold US flight and you arrive more than an hour late, you are usually owed cash — 200% of your one-way fare for shorter delays and 400% for longer ones, each up to a DOT cap. Volunteering is optional; being bumped against your will is what triggers mandatory payment.
Why airlines oversell flights
On most routes a predictable share of passengers do not show up, so airlines sell a few extra seats to fly full. When more people turn up than expected, the flight is “oversold” and the airline has to move some travelers to another flight. How that happens — and what you get — depends on whether you volunteer or are bumped against your will.
Voluntary vs. involuntary bumping
The airline first asks for volunteers to give up their seats in exchange for a travel voucher, miles, or cash, plus a later flight. Volunteering is a negotiation: you can hold out for a better offer, and you should ask for the value in cash or a check rather than a restricted voucher, plus confirmed seats on the next flight and meal or hotel cover if the wait is long.
If not enough people volunteer, the airline chooses passengers to bump involuntarily. That is when federal compensation rules kick in — and the amounts are set by law, not by the gate agent.
How much you are owed (US flights)
For involuntary denied boarding on a flight departing the United States, the Department of Transportation sets minimum cash compensation based on how late the airline gets you to your destination:
- Arrive less than 1 hour late: no compensation is required.
- 1 to 2 hours late (domestic): 200% of your one-way fare, up to a DOT cap.
- More than 2 hours late (domestic), or more than 4 hours internationally: 400% of your one-way fare, up to a higher DOT cap.
The dollar caps are adjusted for inflation every few years, so check the DOT aviation consumer site for the current figures before you accept anything. Crucially, this is cash you can insist on — the airline may offer a voucher instead, often for a larger face value, but you are entitled to a check or the original form of payment if you ask. Take the voucher only if it genuinely suits you.
When compensation is NOT owed
The rules do not apply if you were not at the gate on time, if the aircraft was swapped for a smaller one for safety reasons, if you were offered comparable alternate transport that gets you there within about an hour, or on very small aircraft. They also do not cover a cancellation (that is a refund situation) — only denied boarding on an oversold flight.
How to lower your odds of being bumped
Airlines usually bump the last to check in, passengers on the cheapest fares, and those without assigned seats. To stay off the list: check in right when the window opens, choose your seat in advance, and hold elite status where you can. If you are asked to volunteer and the trip is flexible, it can be a good deal — just negotiate.
How to claim
- Get the compensation at the airport if you can — the airline is generally required to pay involuntary denied-boarding compensation on the day, by check or cash.
- If they offer only a voucher, ask specifically for the cash equivalent you are owed under DOT rules.
- Keep your boarding pass, ticket receipt and any written offer.
- If the airline refuses to pay what the rules require, file a complaint with the US Department of Transportation’s aviation consumer protection office.
Worked example
You hold a $180 one-way domestic ticket and the flight is oversold. Too few people volunteer, so the airline bumps you and rebooks you on a flight arriving three hours late. Because the delay is over two hours, you are owed 400% of your one-way fare — $720 — up to the current DOT cap, in cash. The airline offers a $900 travel voucher instead. If you will use it, take it; if not, insist on the cash you are legally owed. Either way you also keep your seat to your destination.
One safety note
Handle bumping only with the airline’s own gate staff or its verified customer service line. No legitimate airline asks for a fee or your banking login to “release” denied-boarding compensation — that is always a scam.
Frequently asked questions
How much do I get if I'm bumped from an overbooked flight?
For involuntary denied boarding on a US flight, you’re generally owed 200% of your one-way fare for shorter arrival delays and 400% for longer ones, each up to a DOT cap adjusted for inflation — payable in cash.
What's the difference between volunteering and being bumped?
Volunteering is a negotiation — you give up your seat for a payout you can haggle. Being bumped involuntarily against your will is what triggers the federally-set cash compensation.
When is denied-boarding compensation not owed?
If you weren’t at the gate on time, if the aircraft was swapped for safety, on very small aircraft, or if the airline gets you to your destination within about an hour on alternate transport.
