If an airline bumps you from an oversold flight against your will, federal rules entitle you to up to $2,150 in cash, paid on the spot. Airline overbooking compensation is governed by 14 CFR Part 250 and applies to nearly every scheduled flight leaving a U.S. airport on an aircraft with 30 or more seats, whether the carrier is domestic or foreign. The exact amount depends on how late the airline gets you to your final destination, and the payment is supposed to be in your hand before you leave the terminal.
Volunteers and Involuntary Bumps Are Not the Same Thing
Before the airline can bump anyone against their will, it has to ask for volunteers. That’s the gate-agent auction, and there is no legal cap on what the airline can offer. You can negotiate. If nobody bites at a $200 voucher, the offer usually climbs.
One rule protects you here. Before you agree to volunteer, the airline must tell you whether you’d be bumped involuntarily if you don’t raise your hand, and if so, how much mandatory compensation you’d be owed under federal law. Knowing that number is the whole game. A $300 voucher against a $1,000 mandatory cash payout is a bad trade, and you can’t spot it unless you ask.
Only after volunteers fail to free enough seats can the airline start removing people involuntarily. Anyone removed who didn’t volunteer counts as involuntarily denied boarding, and the mandatory compensation rules kick in, even if the passenger accepts the payment without protest.
Who Qualifies for Mandatory Compensation
Not every bumped passenger is owed cash. You have to meet all four of these conditions:
- Your flight originates at a U.S. airport. Flights leaving foreign airports are not covered, even on a U.S. carrier.
- You have a confirmed reservation with a specific flight number in the airline’s system. Award tickets and “zero fare” tickets count.
- You met the airline’s check-in deadline. Deadlines vary, but domestic counter check-in is commonly 45 minutes before departure, with a requirement to be at the gate roughly 15 minutes before departure.
- The aircraft has a designed capacity of 30 or more passenger seats on a scheduled flight.
If you’re on a foreign airline flying from a U.S. airport to an overseas destination, the same framework applies. If the flight originates overseas, it doesn’t, regardless of who operates it.
How Much the Airline Owes You
Compensation is a percentage of your one-way fare to your final destination, including taxes and fees, and it scales with how late you arrive compared to your original scheduled arrival time.
Domestic Flights
- Arrival delay under 1 hour: nothing owed beyond the rebooking.
- Arrival delay of 1 to 2 hours: 200% of your one-way fare, capped at $1,075.
- Arrival delay over 2 hours, or no rebooking offered at all: 400% of your one-way fare, capped at $2,150.
International Flights Departing the U.S.
- Arrival delay under 1 hour: nothing owed.
- Arrival delay of 1 to 4 hours: 200% of your one-way fare, capped at $1,075.
- Arrival delay over 4 hours, or no rebooking offered at all: 400% of your one-way fare, capped at $2,150.
If the percentage of your fare is less than the cap, you get the percentage. If it exceeds the cap, you get the cap. When the airline arranges no substitute flight, the full 400% tier applies no matter when you eventually get there. The caps were last updated in late 2024 based on the Consumer Price Index.
On top of the denied boarding payment, the airline has to refund any ancillary fees you paid for services you won’t receive on the new flight, such as seat upgrades, checked baggage, or priority boarding.
Get Paid in Cash, Not a Voucher
This is where most travelers lose money they’re owed. The airline is required to hand you cash or an immediately negotiable check on the same day the bumping happens, right there at the terminal. It cannot tell you to file a claim and wait.
The one exception is when the substitute flight departs before payment can be prepared. In that case, the airline has 24 hours from the bumping incident to send the money.
Gate agents will often try to hand you a travel voucher or flight credit instead. You are not required to accept one. If you’re considering a voucher anyway, the airline must disclose all material restrictions, including expiration dates and blackout periods, before you agree. And once you accept a voucher as a volunteer, you’ve given up your right to the mandatory cash payment. Know your number before you say yes.
The Written Notice and What to Keep
Right after you’re bumped involuntarily, the airline has to hand you a written statement. It must explain the terms and conditions of denied boarding compensation, describe the airline’s boarding priority rules, and lay out the specific dollar amounts for each delay tier. It also has to tell you that you can decline the airline’s compensation and pursue damages through the courts instead.
Keep that document. If the agent doesn’t offer it, ask for it and cite 14 CFR 250.9. Hold onto your original boarding pass, your electronic ticket receipt showing what you paid, and any rebooking paperwork. If an agent tells you no written notice is required, the agent is wrong.
When No Compensation Is Owed
Several situations let the airline remove you without triggering the payment rules. Airlines sometimes stretch these, so it’s worth knowing which ones genuinely apply.
- Aircraft with fewer than 30 passenger seats are entirely exempt.
- If the airline swaps in a smaller aircraft for operational or safety reasons and it can’t hold everyone, no compensation is owed.
- On aircraft with 60 or fewer seats, passengers removed for safety-related weight and balance reasons aren’t entitled to compensation.
- If you didn’t meet the airline’s ticketing, check-in, or reconfirmation rules, you’re out.
- Moving you to a different cabin class at no extra charge isn’t denied boarding. If you’re moved to a lower fare class, you’re owed a refund of the difference.
- Cancellations are not oversales. A canceled flight is governed by different rules, and the denied boarding compensation framework applies only when the airline sold more seats than the plane holds.
The equipment substitution and weight-and-balance exceptions are the ones airlines lean on most. If your flight was oversold and the airline invokes “safety,” ask what specific condition required the removal and get that answer in writing.
If the Airline Won’t Pay
Start with the airline’s own customer service department, in writing. Federal rules require the airline to acknowledge your complaint within 30 days and send a substantive written response within 60.
If that doesn’t fix it, file a formal complaint with the Department of Transportation’s Office of Aviation Consumer Protection at airconsumer.dot.gov. The DOT will forward your complaint to the airline and require a response to both you and the agency. Airlines that violate the denied boarding rules face civil penalties of up to $75,000 per violation, and each day a violation continues counts as a separate offense. That enforcement threat gives your complaint weight even when the DOT doesn’t open an individual investigation.
When Suing Makes More Sense Than Taking the Cash
The written notice includes a line most travelers miss: you can decline the airline’s compensation and pursue damages in court instead. The statutory amounts are floors on what the airline must offer, not ceilings on what you can recover. If the bump caused you to miss a cruise departure, a non-refundable event, or a business obligation worth far more than $2,150, your actual damages may be much larger.
Suing means giving up the guaranteed statutory payment for the chance at a bigger one, so the math has to work. For a leisure traveler bumped onto a flight two hours later, the cash at the airport is almost always the right answer. When the financial fallout is serious, it’s worth talking to an attorney about a claim for consequential damages before you sign anything.
