Bumped / Involuntary Denied Boarding Compensation Demand (14 CFR Part 250)
The airline bumped you involuntarily — overbooked the flight and you didn't get on. Federal law (14 CFR Part 250) sets mandatory cash compensation, not voucher amounts. Many travelers accept a voucher at the gate without realizing they were owed cash.

[Your Full Name] [Address] [City, State ZIP] [Phone] [Email] [Date] [Airline Name — Customer Relations Department] [Address from contract of carriage] Sent via certified mail, return receipt requested Re: Involuntary Denied Boarding Compensation Under 14 CFR Part 250 — Flight [Number] To Whom It May Concern: I am writing to demand the cash compensation owed to me under 14 CFR Part 250 for the involuntary denied boarding described below. Flight facts: • Confirmation / PNR: [Number] • Flight number: [Number] • Date: [Date] • Origin / destination: [Routing] • Scheduled departure: [Time] • Check-in time (proof I met deadline): [Time, with screenshot/receipt attached] • Boarding priority rule cited (if any): [From airline's published priority list] The IDB: • Date / time bumped: [Date / time] • Airline initially solicited volunteers? [Yes / No] • I was selected involuntarily. Substitute flight: • Flight number: [Number] • Date / time of actual arrival at final destination: [Date / time] • Delta vs. original arrival: [X hours, Y minutes] Compensation owed under 14 CFR § 250.5 (current as of January 22, 2025): [Pick the tier that applies based on delay at final destination.] • 0–1 hour: no compensation owed • 1–2 hr domestic / 1–4 hr international: 200% of one-way fare, max **$1,075** • 2+ hr domestic / 4+ hr international (or no alternate offered): 400% of one-way fare, max **$2,150** One-way fare to destination/first stopover: $[Amount] × tier multiplier (200% or 400%): $[Amount] Capped at: $[$1,075 or $2,150] **Compensation owed**: $[Amount] What was offered at the gate: $[Voucher amount or partial cash] — INSUFFICIENT. Demand: Under 14 CFR § 250.8(a), the airline must offer cash or an immediately negotiable check on the day and place of denial; if the substitute flight leaves before payment can be processed, the airline has 24 hours by mail. Under § 250.9(c), if the airline offers a travel voucher in lieu of cash, the agent must orally tell the passenger of material restrictions on the voucher AND that the passenger is entitled to a check instead. Within [7] days of receipt of this letter, please: 1. Pay $[Amount] in cash or immediately negotiable check (NOT a voucher), per § 250.5; 2. Refund any unused ancillary fees (bags, seat selection, Wi-Fi) per § 250.5(e); 3. Confirm in writing. If you do not, I will file a complaint with the DOT Office of Aviation Consumer Protection at transportation.gov/airconsumer/file-consumer-complaint. DOT actively enforces Part 250 — recent civil penalty actions against airlines for IDB misreporting confirm DOT scrutinizes how gate-side bumps are categorized and documented. Sincerely, [Your Signature] [Your Printed Name] Enclosures: [confirmation; check-in receipt; boarding pass for substitute flight; any written or recorded gate-agent statements; voucher offer documentation]

How to use it
A few things before you send.
- 1.Demand cash, not a voucher. Under 14 CFR § 250.8(a), the airline must pay by cash or immediately negotiable check on the day and place of denial. The voucher offered at the gate is below the statutory floor in many cases — and § 250.9(c) requires the agent to tell you about your cash right.
- 2.Document the check-in time. The airline's #1 defense is that you missed the check-in deadline — which under § 250.6 makes the bump exempt from compensation. Save the boarding-pass screenshot, the check-in confirmation email, the kiosk receipt time.
- 3.If the bump was caused by a smaller aircraft substitution, an unscheduled aircraft change for safety/operational reasons, or weight/balance restrictions on a 60-or-fewer-seat aircraft, Part 250 may not apply. These are the narrow exemptions.
- 4.If you accepted a voucher at the gate without being told of your cash right (§ 250.9(c) was violated), the voucher acceptance is arguably not informed — and you can still demand the cash. Send the letter; airlines often pay the delta to avoid a DOT complaint.
- 5.Send by certified mail with return receipt requested. File a DOT complaint at transportation.gov/airconsumer/file-consumer-complaint in parallel — DOT enforces Part 250 actively, and a DOT file number attached to the dispute often unlocks the cash payment.
What the law actually says
Why this letter works.
14 CFR Part 250 (Oversales) governs what happens when an airline sells more confirmed seats than the aircraft holds and someone is denied boarding. The rule distinguishes voluntary bumping (negotiated; compensation is whatever the passenger accepts) from involuntary denied boarding (mandatory tier compensation under § 250.5, on top of a refund of the unused ticket and any unused ancillary fees). The compensation is the leverage point: many travelers accept a voucher at the gate without realizing they were involuntarily bumped and entitled to a check.
Current compensation tiers (current as of January 22, 2025 per 89 FR 84743). For delays in arrival at final destination of 0–1 hour: no IDB compensation owed. For 1–2 hours domestic / 1–4 hours international: 200% of one-way fare, capped at $1,075. For 2+ hours domestic / 4+ hours international (or where no alternate is offered): 400% of one-way fare, capped at $2,150. These maximums are per passenger and update biennially via CPI. "Fare" under § 250.5(c) means the one-way fare to destination/first stopover, plus surcharges, minus discounts. Compensation is in addition to the value of the original ticket — the passenger keeps the ticket and uses it on the substitute flight, or gets a refund (§ 250.5(d)).
Procedural protections are precise. Under § 250.8(a), payment must be cash or immediately negotiable check on the day and place of denial; if the substitute flight leaves before payment can be processed, the airline has 24 hours by mail. § 250.9(a) requires a written statement of rights to be handed to the bumped passenger explaining IDB compensation and boarding priority. § 250.9(c) requires that if the airline orally offers a travel voucher or free ticket instead of cash, the gate agent must also orally tell the passenger of any material restrictions on the voucher AND that the passenger is entitled to a check instead. This is the disclosure airlines routinely fudge.
Exemptions are narrow but real. Part 250 doesn't apply at all to aircraft with fewer than 30 designed passenger seats, inbound foreign flights to the U.S., or charter and non-scheduled flights. Within Part 250's scope, compensation is not required if the passenger failed to comply with ticketing, reconfirmation, or check-in deadlines (the airline's #1 defense — document your check-in time precisely); if a smaller aircraft was substituted for safety/operational reasons (60-seat-or-fewer aircraft: weight/balance restrictions); if the passenger was re-accommodated in another cabin at no extra charge (downgrade triggers a separate fare-difference refund, not IDB); or if the airline arranged comparable alternate transportation scheduled to arrive within 1 hour of original. Flight cancellation is not an oversale — different remedy under DOT's 2024 cancellation refund rule (14 CFR Part 260).
If this doesn’t work
Your next move.
If the airline ignores the cash demand or stands by an insufficient voucher, escalate. File a DOT complaint at transportation.gov/airconsumer/file-consumer-complaint — DOT actively enforces Part 250 and many disputes resolve once a DOT file number is attached. File an FCBA chargeback for the original ticket if you were never rebooked (within 60 days of statement). For amounts above what the airline pays but within state small-claims limits, file in small-claims court for the statutory IDB amount — Part 250 violations are routinely treated as actionable in small claims under contract-of-carriage breach theories. Some consumer-protection attorneys take systematic IDB-undercompensation cases as class actions, particularly when the airline's voucher-instead-of-cash pattern is well-documented.
Questions people ask
FAQ.
I took a $300 voucher at the gate. Can I still demand the cash?
Maybe. If the agent did not orally disclose your right to a check and any material restrictions on the voucher, § 250.9(c) was violated and the voucher acceptance is arguably not informed. Send the demand letter; airlines often pay the delta to avoid a DOT complaint.
The agent said it was a "weather cancellation," not a bumping.
Cancellations are not IDB. But if the flight actually operated and you were left behind because the airline oversold, that's still IDB regardless of how the agent labeled it. Get a screenshot of the flight status showing it departed.
The plane was a 50-seat regional jet. Am I out of luck?
No — Part 250 applies to aircraft with 30+ seats. The 60-seat threshold is only a defense for the airline when the bump was caused by weight/balance restrictions (§ 250.6(b)). Otherwise the same tier compensation applies.
They put me in business class instead of first. Do I get IDB?
No — that's a downgrade, exempt from IDB under § 250.6(c). You're owed the fare difference refund (a separate right under the airline's contract of carriage and § 250.5(d)).
How fast must they pay?
Same day at the airport, or within 24 hours if your substitute flight departs before they can cut the check (§ 250.8(a)).
