If a covered airline takes your confirmed seat and you didn't volunteer, you may be entitled to compensation. In the United States, 14 CFR Part 250 sets a payment based on your one-way fare and how late the replacement transportation is scheduled to arrive. On qualifying EU261 flights, the usual amounts are a fixed €250, €400, or €600 by distance.
Overbooking by itself isn't the claim. The question is whether the airline involuntarily denied you boarding after you held a confirmed reservation and met its check-in, documentation, and gate rules.
First, identify what happened
Gate staff often use the same "rebooking" language for different events. The paperwork still has to show which one you actually had.
Involuntary denied boarding is when the airline chose not to let you board, usually because more passengers showed up than seats. That's the situation the formulas below address.
If you accepted a later flight, voucher, cash, or other benefit after the airline asked for volunteers, that's voluntary bumping. Your rights then come mainly from the deal you accepted, not from the involuntary scale.
A cancellation or delay that happened before anyone refused you a seat is a different problem. Ordinary delay rules don't automatically create denied boarding pay.
The airline can also refuse boarding for a reason that takes compensation off the table: you missed the check-in deadline, you lacked required travel documents, or you presented a safety or security problem.
Ask the airline to state in writing whether you were recorded as a volunteer or as an involuntary denied passenger. That classification can decide the outcome.
U.S. denied boarding compensation
Covered U.S. flights fall under 14 CFR Part 250. The carrier has to seek volunteers before it selects passengers involuntarily, and the rule sets minimum compensation in qualifying cases.
The amount depends on the scheduled arrival of the replacement transportation compared with the original scheduled arrival:
| Replacement result | Possible federal compensation |
|---|---|
| Replacement arrives within one hour of the original scheduled arrival on a domestic flight | No Part 250 denied boarding payment |
| Replacement arrives more than one hour but less than two hours late on a domestic flight, or more than one hour but less than four hours late on an international flight | 200% of the one-way fare, up to $1,075 |
| Replacement arrives more than two hours late domestically, more than four hours late internationally, or the airline cannot arrange replacement transportation | 400% of the one-way fare, up to $2,150 |
14 CFR § 250.5 has the calculation and the inflation-adjustment method. Check the live rule for the cap in effect on your travel date. Older websites still quote lower figures.
That percentage isn't a second refund of the whole ticket. It's a separate payment calculated from the applicable one-way fare, subject to the legal maximum. If the relevant one-way fare is $300 and a domestic replacement arrives 90 minutes later, 200% would be $600. If the replacement arrives more than two hours later, 400% would be $1,200.
You'll generally need all of the following for Part 250 to apply:
- A confirmed reservation and valid ticket
- Check-in and arrival at the gate by the airline's stated deadlines
- Compliance with travel-document, security, and boarding requirements
- An involuntary refusal of boarding on a flight within the scope of Part 250
The rule has exceptions. It doesn't cover every flight or every reason for refusing boarding. The operating carrier, departure airport, aircraft, and reason for the refusal matter. Buying on a U.S. website or with a U.S. card doesn't by itself pull a foreign flight under U.S. oversales rules.
If the denial was involuntary, the airline must explain the compensation amount and your payment options. A voucher often appears first. Don't assume you have to take it instead of the cash or check amount the rule requires. Read the terms before you sign a waiver.
U.S. law also doesn't create a standard extra payment because a family was separated or the replacement flight was inconvenient. Airline policy might address those issues. They don't change the Part 250 formula.
EU261 and UK261 overbooking rights
EU261 generally covers flights departing from an EU airport, regardless of the airline, and flights arriving in the EU from outside the EU when an EU airline operates them. The official Your Europe air passenger rights guidance explains coverage and remedies. The United Kingdom has a separate UK261 framework that is similar in several respects, but the enforcement route depends on the itinerary and the carrier.
If you had a confirmed reservation, arrived on time with the required documents, and were involuntarily denied boarding, the usual EU261 compensation is:
| Flight distance | Standard compensation | Possible reduced amount after timely rerouting |
|---|---|---|
| Up to 1,500 km | €250 | €125 |
| More than 1,500 km within the EU, or other flights between 1,500 and 3,500 km | €400 | €200 |
| Other flights over 3,500 km | €600 | €300 |
The airline may cut the payment by 50% if its rerouting gets you to your final destination within the applicable delay limit. Those limits are generally two hours for the shortest flights, three hours for the middle band, and four hours for longer flights.
That compensation sits beside a separate choice: reimbursement of the ticket where applicable, rerouting at the earliest opportunity, or rerouting on a later date that suits you, subject to availability.
While you wait, the airline may also owe reasonable meals, refreshments, communications, and hotel accommodation when an overnight stay is necessary. Ask the airline to provide this assistance. If you pay yourself, keep itemized receipts and skip unreasonable upgrades.
A refusal based on inadequate travel documents, security, safety, or health concerns is not an oversale and may not qualify. A passenger who accepted a volunteer arrangement normally receives the benefits agreed with the airline rather than the fixed involuntary payment.
What to do at the airport
If the airline asks for volunteers, get the complete offer in writing before you agree. Check the cash or voucher value, whether the amount is per passenger, expiration dates and travel restrictions, the replacement flight and confirmed seat, meal, hotel, baggage, and ground-transport arrangements, and whether accepting the offer waives other claims. If the airline selected you rather than asking you to volunteer, say clearly that you do not agree to surrender your seat voluntarily.
Ask for a written denied boarding notice with the airline and flight number, date and route, your confirmed reservation and check-in status, whether the denial was voluntary or involuntary, the reason, the replacement flight and its scheduled arrival, and the compensation calculation and payment method. Covered U.S. carriers have to provide written information about involuntary denied boarding rights. Even where no specific form appears, requesting one creates a useful record.
Photograph or screenshot your boarding pass, reservation, gate display, and rebooking details. The scheduled arrival of the original and replacement flights can change the U.S. payment tier and any EU261 reduction. Write down when you arrived at the airport and gate, when boarding closed, what you were told, and the names or employee numbers of staff who handled the case.
Don't treat compensation and transportation as the same issue. You may have a right to a payment for being bumped and a separate right to reimbursement or rerouting, depending on the rule that applies. If you no longer want to travel, ask specifically about a ticket refund. If you take a replacement flight, keep the new boarding pass and confirmation. Don't rely on a verbal promise that the airline will pay later.
On a qualifying EU261 itinerary, request meals, refreshments, and hotel accommodation when appropriate. In the United States, Part 250 sets denied boarding compensation but doesn't automatically require every airline to pay meals or hotels for every bump. Ask about the carrier's policy and keep any written promise.
Keep the original ticket receipt, boarding passes, denial notice, volunteer offer, rebooking record, receipts, and email or chat messages. Scan or photograph paper documents before handing them over.
How to file the claim
Submit the claim to the airline that operated the flight and denied boarding, even if you bought the ticket through a travel agency or another airline's website. The ticket seller may need to handle a payment or booking problem, but the operating carrier controls the boarding decision.
Use the carrier's official customer-relations, denied boarding, or compensation form. Attach copies of your evidence and keep the submission confirmation. Ask for each remedy separately: the applicable Part 250 payment or EU261 compensation; reimbursement or rerouting if that's still unresolved; reimbursement for eligible meals, lodging, or transportation; and a written explanation if the airline says you were exempt.
A short claim is easier to assess than a long narrative. You can use wording such as:
I had a confirmed reservation on [flight number] on [date], checked in by the stated deadline, and arrived at the gate on time. I was denied boarding involuntarily because the airline could not provide my confirmed seat. The replacement transportation was scheduled to arrive at [time], compared with the original scheduled arrival of [time]. Please pay the applicable denied boarding compensation and confirm the calculation. My supporting documents are attached.
If you accepted a voucher at the airport, include its terms and explain whether the airline presented it as a voluntary settlement. Don't describe an involuntary bump as a voluntary change just because staff used a general "rebooking" form.
If the airline denies the claim
Ask it to identify the exact reason. Common explanations are that you volunteered, that records show you checked in or reached the gate late, that the reservation was not confirmed, that a documentation, safety, or security exception applies, that the replacement-flight delay was calculated incorrectly, or that the incident was a cancellation rather than denied boarding.
Respond with the document that addresses that reason. Send your check-in timestamp if the airline says you were late, or your confirmation email if it says the reservation was unconfirmed. Request a revised calculation rather than merely asking for goodwill.
For a U.S. dispute, you can file a complaint with the Department of Transportation after giving the airline a reasonable opportunity to respond. A DOT complaint can help identify a regulatory issue. It isn't the same as a court judgment ordering an individual payment.
For an EU261 dispute, use the airline's approved alternative dispute resolution process where available, or contact the national enforcement body connected with the relevant flight. The Your Europe guidance can help identify the authority. Court deadlines and procedures vary, so don't assume a general two-year or six-year deadline applies to every claim.
A claims company can submit paperwork, but it can't create eligibility. Before signing, check its percentage fee, whether tax or voucher amounts are included in the fee, and whether you are assigning the claim or only authorizing representation.
Deadlines and evidence
There is no single worldwide deadline for overbooking compensation.
Part 250 sets the U.S. payment rules, but the carrier's claim procedure, contract, and applicable law can affect how and when you must pursue the payment. In the EU, the limitation period comes from the relevant national law and can differ by country; EU261 itself shouldn't be treated as a universal two-year deadline. UK261 is separate, and the applicable limitation period depends on the claim and legal route. Other countries apply their own aviation and contract rules.
File while you still have the airport documents and exact rebooking times. A late claim can be harder to prove even when no clear statutory deadline has passed.
What does not create an automatic payout
An airline's overbooking rate doesn't prove that your individual bump qualifies. A compensation calculator can estimate distance or fare, but it can't prove the denial was involuntary. A delayed flight isn't automatically an overbooking claim, and a voucher's advertised value isn't necessarily the same as statutory cash compensation.
The Montreal Convention does not provide a standard overbooking payment like €250, €400, or €600. It may be relevant to proven losses from certain international delays or other covered events, but it isn't a universal fallback for a bumped passenger. A booking site's location doesn't determine which passenger-rights law applies.
The strongest file usually has a confirmed reservation, timely check-in, proof the airline selected you involuntarily, the original and replacement schedules, and the written compensation calculation.
Quick answers
Can I claim if I volunteered to give up my seat?
You can enforce the terms of the deal you accepted, but the fixed involuntary payment generally isn't the starting point. Compare the offer with what might have applied if the airline had selected you involuntarily.
Can I receive compensation and a refund?
They are different remedies. On qualifying EU261 itineraries, compensation can sit beside reimbursement or rerouting. In the United States, ask the airline to address the ticket refund and the Part 250 payment as separate issues. The correct result depends on the transportation you accepted and the ticket used.
Is the airline required to pay in cash?
For qualifying involuntary U.S. denied boarding, the airline must disclose the cash or check amount and can't simply assume a voucher is acceptable. Under EU rules, a voucher normally requires your agreement.
Save the reservation, boarding pass, denial notice, replacement itinerary, and receipts. File directly with the operating airline, state that the denial was involuntary, and ask it to show the calculation under the rule that matches your flight.
