When a US flight falls apart, the most valuable thing you can have is a clear picture of what you are actually owed — and what you are not. The short version: a cancelled or significantly changed flight you choose not to take means an automatic cash refund, but the US has no general right to cash compensation for delay the way Europe does. Knowing that difference stops airlines from fobbing you off with a voucher.
This article explains US federal consumer-protection rules for general information; it is not legal advice. Rules change and have fare-class and operational exceptions — always confirm with the US DOT Aviation Consumer Protection office and your airline for your specific situation.
When are you entitled to a refund?
The DOT’s automatic refund rule, which took effect in late 2024, is the strongest right you have. You are owed a prompt, automatic refund to your original payment method when:
- The airline cancels your flight and you do not accept rebooking or a travel credit.
- The airline makes a significant change to your itinerary and you decline it. For the refund rule, a significant change generally includes:
- A departure or arrival time that moves by 3+ hours (domestic) or 6+ hours (international).
- A change in the departure or arrival airport.
- Added connections, or a downgrade to a lower class of service.
- You paid for a service the airline did not provide (for example, Wi-Fi or seat selection).
- Your checked bag is significantly delayed and you filed a report.
| Disruption | What you are owed |
|---|---|
| Flight cancelled, you don’t rebook | Full automatic refund to original payment |
| Delay 3+ hrs domestic / 6+ hrs intl, you don’t travel | Full automatic refund |
| Checked bag not delivered in time (12 hrs domestic) | Refund of the checked-bag fee |
| Paid ancillary not delivered (Wi-Fi, seat) | Refund of that fee |
| Delay where you still fly | No required cash compensation (see below) |

How fast must the refund arrive, and in what form?
The rule is specific. Refunds must be:
- In the original form of payment — cash, the card you used, or miles. The airline cannot push a voucher or travel credit on you unless you choose it.
- Automatic — you should not have to fight for it.
- Prompt — generally within 7 business days for credit-card purchases and 20 calendar days for cash or check payments.
If an airline tries to issue a voucher when you asked for your money back, that is the line to push on.
Does the US require cash compensation for delays? (No.)
This is the biggest misconception in US air travel. There is no US equivalent of the EU’s EC 261, which pays fixed cash sums (often €250–€600) for long delays caused by the airline. In the US:
- A refund is only triggered when you do not travel. If you wait out a 4-hour delay and fly, no refund is owed for the delay itself.
- For controllable disruptions (mechanical issues, crew/staffing, IT outages — things within the airline’s control, as opposed to weather or air-traffic control), airlines are not required by law to pay you cash. Instead, the major carriers have made voluntary commitments to rebook you for free and provide meals and overnight hotels when they cause a long delay or overnight cancellation.
The DOT publishes exactly what each airline promises on its Airline Cancellation and Delay Dashboard (transportation.gov/airconsumer). As of 2024–2025, competition there produced commitments to rebooking, meals and hotels — but no major US airline committed to cash compensation for controllable delays. The FAA Reauthorization Act of 2024 codified the framework that holds airlines to the promises they publish.
Controllable vs. uncontrollable: why it matters
Your care entitlements hinge on the cause:
- Controllable (airline’s fault): maintenance, crew/staffing, airline IT problems. Expect free rebooking, and meal/hotel coverage per the airline’s commitment.
- Uncontrollable: weather and most air-traffic-control / National Airspace System delays. Airlines will rebook you, but meal and hotel coverage is generally not promised.
Either way, if the flight is cancelled or significantly changed and you opt out of travel, the refund right still applies — the cause does not remove your refund.
A practical checklist when your flight is disrupted
- Decide: rebook or refund. If you no longer want to travel on a cancelled/significantly-changed flight, decline the rebooking and request a refund to your original payment.
- Get it in writing. Save the cancellation/change notice and any communications.
- Check the DOT dashboard for your airline’s meal/hotel commitments if the cause is controllable.
- Claim bag-fee refunds if a checked bag arrives outside the DOT window.
- File a complaint with the DOT Aviation Consumer Protection office if the airline refuses what you are owed.
The bottom line
In the US, your hard right is the automatic refund for flights you don’t take after a cancellation or significant change — paid in your original form of payment, not a voucher. There is no automatic cash payout for delays themselves; meals, hotels and rebooking depend on the airline’s published commitments.
