Your Flight Is Delayed or Cancelled. Here's Exactly What You're Owed.

United States: You have a strong right to a refund if your flight is cancelled or significantly delayed. You have no legal right to cash compensation for the delay itself - regardless of how long it lasts or whether it was the airline's fault.

European Union: You have the right to a refund AND up to €600 per person in cash compensation for delays of 3+ hours - on top of meals, hotel accommodation, and rebooking. A family of four on a cancelled transatlantic flight can claim €2,400 in total compensation.

That gap is not a small difference in fine print. It's the difference between recovering your ticket price and recovering your ticket price plus a substantial cash payment. And it applies to millions of American passengers flying to and from Europe who have no idea these rules exist.

📌 The most important thing to know before reading further: do not accept a voucher or travel credit without being told - in writing - that you are entitled to a cash refund instead. Both US and EU rules give you the right to cash. Airlines routinely offer vouchers first because many passengers accept them without asking.

Here is what US rules require for domestic and US-point-of-sale travel, refunds for significant changes, what is not covered, and voluntary airline promises on the DOT dashboard.

Under the DOT's Automatic Refund Rule (fully in effect since October 2024), if your flight is cancelled or significantly changed and you choose not to travel, you are entitled to a full cash refund - even on a non-refundable ticket - to your original form of payment. ^[1]

A 'significant change' that triggers refund rights is defined as:

How quickly must refunds be processed? Within 7 business days for credit card purchases. Within 20 calendar days for other payment methods (cash, check, debit). Airlines can no longer substitute vouchers or travel credits without your explicit consent. ^[1]

⚠️ Critical: If you accept rebooking on an alternative flight, you lose your right to a cash refund. Airlines are required to inform you of your refund right when offering rebooking. If they don't, and you take the rebooked flight, you may still be able to dispute ancillary fees charged for services not received - but the base fare is no longer refundable once you accept alternative travel.

Here is where US law falls dramatically short of European standards. There is no federal requirement for airlines to compensate passengers financially for flight delays, regardless of cause or length. A 6-hour delay caused entirely by the airline's scheduling failure entitles you to exactly: nothing extra. ^[2]

The Biden administration proposed mandatory compensation for airline-caused delays in 2024. The Trump administration scrapped that rule in late 2025. A coalition of Democratic senators is now pursuing legislation to reinstate it, but as of April 2026, no such requirement exists. ^[3]

What airlines have voluntarily committed to (not legally required, but publicly promised on the DOT dashboard at flightrights.gov):

One consumer-friendly rule that did make it through: if your checked bag is not delivered within 12 hours of your domestic flight arriving at the gate (or 15–30 hours for international, depending on flight length), you are entitled to a refund of your bag fee. You must file a mishandled baggage report with the airline. ^[1]

Also refundable: any ancillary fees for services not provided - Wi-Fi that didn't work, seat upgrades that weren't available, lounge access you couldn't use. These are automatic refund entitlements under the 2024 DOT rule.

Involuntary bumping - being denied boarding against your will on an oversold flight - is the one situation where US law does require cash compensation. The amounts depend on your delay to final destination: ^[2]

EU Regulation 261/2004 - universally called EU261 - is the most passenger-friendly aviation law in the world. It has been in force since 2005 and applies to a much broader set of flights than most Americans realise. ^[4]

Your citizenship is completely irrelevant. EU261 does not care whether you are American, British, French, or any other nationality. What determines whether EU261 applies is the route and the airline - nothing else. An American and a French citizen sitting next to each other on the same flight have identical rights under EU261.

Two rules determine coverage. If either one applies to your flight, EU261 applies to you:

Rule 1 - Departure: Your flight departs from an EU, UK, Swiss, Norwegian, or Icelandic airport. ALL airlines are covered under this rule - including US carriers like Delta, United, and American.

Rule 2 - Arrival + Carrier: Your flight arrives at an EU/UK/Swiss/Norwegian/Icelandic airport AND is operated by an EU or UK-based carrier. This covers flights departing from non-EU countries (like the US) on qualifying carriers.

📌 The single most important thing to check: If your flight departs from a European airport, EU261 applies regardless of which airline you're on. If your flight departs from a US airport, EU261 only applies if your airline is European (e.g. Lufthansa, Air France, KLM, British Airways, Iberia, Ryanair).

Check your specific route:

Practical takeaway for transatlantic travellers: Flying to Europe on a US carrier (Delta, United, American) means no EU261 on the outbound journey. EU261 applies on the return because you depart from a European airport. Flying on a European carrier (Lufthansa, Air France, KLM, British Airways) means EU261 applies in both directions. This is one reason frequent transatlantic travellers often prefer European carriers - the consumer protection is substantially stronger.

💡 The delay clock runs to your FINAL destination, not your departure. If your London–New York flight departs 3 hours late but lands only 2 hours 50 minutes late (thanks to a fast jet stream), you do not qualify. If you depart on time but miss a connection and arrive 4 hours late overall, you do qualify. Airlines know this and count on passengers not understanding it.

Separate from cash compensation, EU261 requires airlines to provide care whenever a delay reaches certain thresholds - regardless of whether the delay qualifies for cash compensation:

Since Brexit, UK passengers flying within or to/from the UK are covered by the equivalent UK261 regulation. The amounts are in pounds and slightly lower at current exchange rates: ^[4]

Regardless of where you're flying or what the airline's rules say, your credit card may provide significant additional protection - particularly if the airline goes out of business or refuses to issue a refund you're entitled to.

Fair Credit Billing Act (FCBA) - Chargebacks

If an airline cancels your flight and refuses to provide the refund you're owed, you can dispute the charge with your credit card issuer under the Fair Credit Billing Act. The issuer can reverse the charge within 30–60 days. You generally have 60 days from the first statement listing the charge to initiate a dispute. ^[5]

How to file: Contact your card issuer, state that the service was not provided, cite the FCBA, and request a chargeback. You do not need the airline's approval.

Debit cards: Significantly weaker. Debit card issuers have no legal obligation to reverse charges and the FCBA protections are narrower. Always book flights on a credit card.

Travel Insurance - The Fastest Route in Some Cases

Comprehensive travel insurance policies that include trip interruption and delay coverage can reimburse hotel, meal, and transportation costs during significant delays - often faster than the airline's own processes. Some premium credit cards include travel delay insurance automatically (Chase Sapphire Preferred, Chase Sapphire Reserve, Amex Platinum, and others).

If you're flying EU261-covered routes, check whether your travel insurance covers the claims process - some policies include claims-filing assistance for EU261 cases.

Knowing your rights is step one. Collecting them requires a specific process.

Get the reason in writing. Ask the gate agent for written confirmation of the delay cause. 'Operational reasons' and 'crew scheduling' are airline-caused - document this. Weather causes will be harder to claim under EU261 but may still qualify for voluntary airline assistance.

Keep all receipts. Meals, hotel, transportation - every expense incurred because of the delay. US airlines have no legal obligation to reimburse these, but EU261 requires it, and your credit card's travel delay insurance may cover them.

Request care from the airline. For EU flights, explicitly ask for meal vouchers and hotel accommodation if you qualify. Airlines don't always offer proactively - you have to ask.

Do not accept a voucher without asking about cash. Say: 'Am I entitled to a cash refund?' If yes, ask for it in that form. Vouchers may not be redeemable after a period or if the airline goes bankrupt.

US domestic: Contact the airline's customer service. Cite the DOT Automatic Refund Rule. If they refuse a legitimate refund, file a complaint at transportation.gov/airconsumer. If still unresolved, file a credit card chargeback.

EU261: File directly with the airline first - use their online claim form. If rejected within 8 weeks, escalate to the National Enforcement Body in the departure country (e.g., the CAA in the UK, DGAC in France, Luftfahrt-Bundesamt in Germany). Many passengers use third-party services (AirHelp, ClaimCompass, Flightright) which take 20–30% of the payout but handle the process entirely.

Credit card chargeback: If the airline owes you a refund and isn't paying, initiate a chargeback with your credit card issuer within 60 days of the first statement.

Small claims court: For US domestic claims under $10,000 where the airline refuses a legitimate refund, small claims court is an option. Airlines frequently settle rather than appear.

💡 Time limits for EU261 claims vary significantly by country: from 1 year in Belgium to 6 years in England and Wales. File as early as possible regardless. Most third-party claims services can go back several years, but earlier claims are faster to resolve. For US DOT complaints, file within 30 days of the flight where possible.

The US system protects your money when you choose not to fly - you'll get your ticket price back if your flight is cancelled and you decline rebooking. It does not compensate you for your time, your missed connections, your hotel rooms, or your rescheduled plans.

The European system does both - and does it in cash, not vouchers, with amounts that can meaningfully exceed the original ticket price.

If you fly internationally, especially to and from Europe, learning EU261 is worth more than any other single piece of travel knowledge. A family of four on a disrupted transatlantic trip that qualifies for full EU261 compensation could walk away with €2,400 in cash that most passengers never claim.

Always use a credit card for flights. Always keep receipts. Always ask about cash before accepting a voucher. The rules are on your side more than most airlines would like you to know.
