DOT Bumping Compensation: Your Rights When an Airline Involuntarily Bumps You

Involuntary denied boarding (IDB), commonly called 'bumping,' occurs when an airline has sold more tickets for a flight than it has seats, and not enough passengers voluntarily give up their seats. The airline then denies boarding to one or more passengers against their will.

Important distinction: Bumping rules apply to involuntary denial. If you accepted a voucher to voluntarily give up your seat, different rules apply and the compensation is whatever the airline offered.

Federal rules at 14 CFR Part 250 require airlines to compensate passengers who are involuntarily denied boarding on domestic and international flights. See the US passenger rights guide for the full regulatory framework.

Compensation is calculated based on the type of flight (domestic or international) and how long the airline delays your arrival at your final destination:

• ›

  Domestic, delay under 1 hour: No compensation required

• ›

  Domestic, delay 1 to 2 hours: 200% of one-way fare, maximum $775

• ›

  Domestic, delay over 2 hours: 400% of one-way fare, maximum $1,550

• ›

  International, delay 1 to 4 hours: 200% of one-way fare, maximum $1,550

• ›

  International, delay over 4 hours: 400% of one-way fare, maximum $3,100

The 'one-way fare' used for the calculation is the fare you paid for the segment you were bumped from, not the round-trip price. The DOT adjusts these caps periodically for inflation. The current figures apply to flights operated as of 2024.

DOT rules require that compensation be paid as cash or a check at the airport, on the day of the incident. The airline must make payment before the substitute transportation departs.

Your right: You can demand cash or a check. The airline may offer a voucher for future travel, but you are not required to accept it instead of cash. If you accept a voucher, you waive your right to the cash compensation.

If the airline offers a travel voucher and you are unsure of its real value, ask for cash instead. Vouchers often come with blackout dates, expiration dates, and restrictions that reduce their actual value compared to cash.

Not every denied boarding situation triggers DOT compensation. Exceptions include:

• ›

  Aircraft with 60 or fewer seats (regional jets and turboprops on some routes are exempt)

• ›

  Charter flights

• ›

  Flights where you were bumped for safety or security reasons (disruptive passenger, weight and balance issues)

• ›

  Passengers who did not have a confirmed reservation or did not check in on time

• ›

  Passengers who were offered a substitute flight that arrives within 1 hour of the original (domestic) or within 4 hours (international)

The exemption for small aircraft is significant on regional routes. If you are bumped from a regional jet operated by a code-share partner, check whether the aircraft has more than 60 seats before assuming compensation applies.

Airlines are required by DOT rules to first seek volunteers before involuntarily bumping passengers. The airline offers vouchers or miles to passengers who agree to give up their seats. If enough volunteers come forward, no one is involuntarily bumped.

If you accepted a voucher voluntarily, the compensation is whatever the airline offered, not the statutory IDB amounts. Make sure you understand whether you are volunteering before you accept any offer from an airline gate agent.

Tip: If the airline offers a voucher at the gate and you did not explicitly agree to be bumped, you may still be entitled to IDB compensation. Ask whether you are being classified as voluntary or involuntary.

If the airline bumps you involuntarily, follow these steps:

1. 1

   Ask the gate agent to classify your denied boarding as involuntary

2. 2

   Request the IDB compensation statement (airlines are required to provide one)

3. 3

   Request cash or a check, not a voucher

4. 4

   Accept the substitute transportation and document your actual arrival time

5. 5

   If the airline refuses to pay the correct amount, file a DOT complaint

If the airline later refuses to honor the compensation, consider small claims court. The statutory amounts are clear and courts routinely award them. See small claims court vs DOT complaint for a comparison of escalation paths.

Airlines are required by DOT rules to provide a written notice (the IDB compensation statement) that explains the compensation rules, the amount owed, and how to claim it. If the airline tries to rush you through without providing this document, ask for it specifically.

Airlines must also post their denied boarding policies and display a notice at all gate areas where passengers board. If you want to review the specific rules before you travel, you can read 14 CFR Part 250 at the Electronic Code of Federal Regulations.
