Diverted flights, delays and cancellations: what you're owed

The DOT refund rule is your baseline

Since October 2024, the U.S. Department of Transportation requires airlines and ticket agents to issue automatic, prompt cash refunds when a flight is canceled or significantly changed and you don't accept the alternative offered. That includes tickets sold as non-refundable — the rule overrides the fine print.

'Significant change' is defined by the DOT and covers departure or arrival time shifts of 3+ hours domestic (6+ international), a change in origin or destination airport, added connections, a downgrade in cabin class, or a switch to a less accessible aircraft. A diversion that ends your trip at a different airport than the one you booked qualifies.

Refunds must be issued within 7 business days for credit-card purchases and 20 days for cash or check, in the original form of payment. Airlines cannot force you into a voucher or travel credit. If they try, that's the moment to file a complaint — see the escalation section below.

EU261: cash on top of the refund

EU Regulation 261/2004 is the strongest passenger-rights law in the world and it can apply to your trip even if you're American. It covers any flight departing an EU airport (on any airline) and any flight arriving in the EU on an EU-based carrier. The UK has a near-identical version (UK261) post-Brexit.

When a flight is canceled with less than 14 days notice, or is delayed 3+ hours at arrival, and the cause is within the airline's control (mechanical issues, crew scheduling, most operational problems), passengers are owed fixed cash compensation regardless of ticket price:

• €250 — flights up to 1,500 km
• €400 — intra-EU over 1,500 km, or other flights 1,500–3,500 km
• €600 — flights over 3,500 km outside the EU

'Extraordinary circumstances' — weather, ATC strikes, security alerts — exempt the airline from the cash comp, but you still get rerouting, meals, and hotel accommodation. Diversions that add 3+ hours to your arrival typically qualify for EU261 comp on covered routes.

What the airline's own policy adds

Beyond the DOT rule, U.S. airlines publish 'customer service plans' the DOT tracks on its Airline Customer Service Dashboard. Most major carriers now commit — in writing — to rebooking on their own flights at no cost, meal vouchers after a 3-hour controllable delay, and hotel plus ground transport for overnight controllable delays. A few (Alaska, JetBlue) also give travel credits or miles for long delays. Spirit and Frontier commit to less; check before you fly.

What airlines rarely advertise: many will rebook you on a different carrier if their own next flight is too far out. This is called an interline rebook or a 'flat-tire rule' waiver, and gate agents can do it but usually won't offer. Ask directly: 'Can you interline me on the next available flight, any carrier?'

How to actually file the claim

Speed matters. Start the process while you're still at the airport if you can — screenshots of departure boards, boarding passes, and rebooking offers are your evidence.

1. Screenshot the delay/cancellation notice from the airline app and the departure board. Save your boarding pass and receipts (meals, hotel, rideshare).
2. Open the airline app or website and look for 'request a refund' or 'travel disruption.' Submit the refund request — do not accept a voucher if you want cash.
3. If you're on an EU-covered route, submit a separate EU261 compensation claim through the airline's dedicated form (search ' EU261 claim').
4. Keep receipts for reasonable expenses (meals, hotel, transport). Most airlines reimburse up to $50/meal and full hotel for controllable overnight delays; submit them via the same disruption form.
5. Note the date. Airlines have 7 business days (credit card) or 20 days (cash) to refund, and EU261 claims should be resolved within 30 days.
6. If nothing happens, escalate — see below.

Your credit card and travel insurance

If you paid with a card that includes trip delay or interruption insurance, you may have a second layer of coverage on top of what the airline owes. Chase Sapphire Preferred, United Explorer, Amex Platinum, and a handful of others reimburse meals, hotels, and incidental costs after a 6- or 12-hour delay, typically up to $500 per person. This is on top of any airline reimbursement — you don't have to choose.

File the card claim through the benefits administrator (usually a link on the card's benefits page). You'll need: itinerary, proof of delay (an email from the airline works), and itemized receipts. Deadlines are strict — most cards want the claim within 20–60 days.

Standalone travel insurance and 'cancel for any reason' policies operate separately and usually require the airline refund to be processed first. Read the policy — coverage caps and 'covered reasons' vary widely. If you're claiming both, be honest: double-dipping the same loss is insurance fraud.

When the airline says no: escalation ladder

Airlines deny valid claims all the time — banking on the fact that most people give up. Don't. Every step below is free and effective.

• DOT complaint — File at transportation.gov/airconsumer. Airlines are required to respond within 60 days, and the DOT tracks complaint volume publicly, which motivates real answers.
• Credit-card chargeback — If the airline canceled and won't refund, dispute the charge with your card issuer under Reg Z 'services not rendered.' You typically have 60 days from the statement date.
• State attorney general — For repeated bad-faith denials, especially involving elderly or disabled passengers, file with your state AG's consumer protection division.
• EU261 claim companies — AirHelp, ClaimCompass, and Flightright will pursue EU261 claims for 25–35% of the payout. Only worth it if you've been denied directly and don't want the hassle.
• Small claims court — For clear DOT rule violations, small claims (under $5,000–$10,000 depending on state) is cheap and airlines rarely show up.

Class actions occasionally form around systemic airline misconduct (see how to check if you're part of a class action) — for example, when a carrier retains fees illegally or misrepresents delay causes.

Other money the airline may owe you

Bag fees are refundable if your checked bag is 'substantially delayed' — the DOT's 2024 rule defines this as 12 hours for domestic and 15–30 hours for international. Wi-Fi and seat-selection fees are refundable when the service wasn't provided (broken Wi-Fi, seat downgrade, involuntary reassignment). Most travelers never ask.

If the delay disrupted a paid connection outside the itinerary (a cruise, a hotel non-refundable night, a concert), the airline generally isn't liable — that's what trip insurance is for. But if the missed connection was on the same reservation, the airline is on the hook to get you there.

While you're in the mindset of recovering money, it's worth checking the broader landscape of open class-action settlements and the growing list of no-proof settlements anyone can claim. Owed can scan for these automatically — see what you're owed in about 30 seconds, or browse the current settlements directory.

This is general information, not legal advice. Refund and compensation rights depend on your specific ticket, route, and the cause of the disruption.
