For an eligible passenger involuntarily denied boarding because a flight is oversold, compensation depends on the one-way fare and arrival delay. Domestic delays of one to two hours and qualifying international delays of one to four hours pay 200% of the one-way fare, capped at $1,075. Longer delays pay 400%, capped at $2,150. No compensation is required when alternative transportation arrives within one hour.
Passengers report confusion when one traveler is labeled involuntary and a companion is labeled voluntary, changing payment from required cash compensation to a negotiated voucher. The exact status and new arrival time must be written down.
Start here: a practical action plan
- Save the original booking, receipt, itinerary, and every change notice.
- Calculate the refund or claim with written assumptions and timestamps.
- Check current federal guidance and the carrier or lodging terms.
- Submit the documented request and reconcile the payment received.
- A voucher accepted before the cash-refund choice is understood.
- A liability ceiling treated as a guaranteed reimbursement amount.
- A U.S. rule applied to an itinerary outside its geographic scope.
Confirm that the bump qualifies
Federal denied-boarding compensation applies to specific oversales situations. The traveler must have a confirmed reservation, check in and reach the gate on time, depart from a U.S. airport, and be unable to reach the destination within one hour of the original arrival because the airline required the seat back.
Aircraft substitutions, weight and balance limits on small planes, charter flights, very small aircraft, and flights departing a foreign location can fall outside the U.S. compensation rule. Read the eligibility list before multiplying the fare.
Worked example: apply the percentage and cap
Example: the one-way fare for an oversold domestic flight is $390. The airline's substitute transportation reaches the destination 3 hours 20 minutes after the original arrival. That exceeds two hours, so the calculation is 400% x $390 = $1,560.
Because $1,560 is below the current $2,150 cap, the example required payment is $1,560. If the one-way fare were $700, four times the fare would be $2,800, but the airline could limit the required amount to $2,150.
| Hypothetical domestic bump | Calculation | Result |
|---|---|---|
| One-way fare | $390 | |
| New arrival delay | 3 hours 20 minutes | |
| Applicable percentage | 400% | 4 x $390 |
| Calculated payment | $1,560 | |
| Current longer-delay cap | $2,150 | |
| Required example amount | Lower of calculation or cap | $1,560 |
Do not confuse volunteers with involuntary bumps
Volunteers negotiate compensation rather than using the involuntary formula. Before accepting a volunteer offer, get the exact amount, form, expiration, restrictions, confirmed substitute flight, and treatment of companions. A vague promise of at least a certain amount is not a final agreement.
If only one person in a party is selected, do not let a request to travel together silently convert the companion into a volunteer. Ask the gate agent to identify each traveler's status in writing and explain the choices before tickets are changed.
Collect the written notice and same-day payment
Eligible compensation should be offered at the airport on the same day. If substitute transportation leaves before payment can be made, the airline must pay within 24 hours. Ask for the written statement describing rights and how the amount was calculated.
Denied-boarding compensation does not automatically pay every missed reservation, hotel, or consequential loss. Keep those costs separate and check the airline's contract, travel insurance, and any foreign passenger-protection regime that also may apply.
- Confirm oversales eligibility and on-time check-in.
- Record the substitute flight's destination arrival time.
- Multiply the one-way fare by the applicable percentage.
- Obtain each traveler's status, calculation, and payment in writing.
Frequently asked questions
Who qualifies for involuntary denied-boarding compensation?
An eligible, on-time passenger with a confirmed reservation who is required to give up a seat on an oversold flight departing a U.S. airport can qualify.
How much is paid for a domestic delay over two hours?
The formula is 400% of the one-way fare, with the airline allowed to cap the required payment at $2,150.
What if the substitute flight arrives within one hour?
Federal denied-boarding compensation is not required when the airline gets the passenger to the destination within one hour.
Is volunteer compensation calculated the same way?
No. Volunteers negotiate the amount and terms. Get the payment form, restrictions, and substitute itinerary before agreeing.
When must eligible compensation be paid?
The airline should offer payment the same day at the airport, or within 24 hours if substitute transportation departs first.
Does the rule apply to a flight departing Europe for the United States?
The U.S. rule does not cover flights departing a foreign location, though another country's protections or airline policy may apply.
