Flight Delay & Cancellation Compensation: Your Rights in 2026 (US & UK)

If United cancels your $480 Chicago–Denver flight and you choose not to rebook, US DOT rules now require an automatic refund to your original payment method — cash, not a voucher, not a credit, with no form to fill out. And if British Airways delays your London–New York flight by more than three hours for a reason within its control, UK261 can owe you up to £520 in cash compensation on top of getting you there. Most travellers never claim either, because they don't know the rules exist. Here's the full map for 2026.

Flight compensation is the money or refund an airline owes you when it cancels, significantly delays, or denies you boarding. Two completely different regimes apply depending on where you fly: the US DOT automatic-refund rule (for US flights) and UK261 / EU261 (for UK and EU flights). They protect different things, so know which one covers your trip.

The US regime: automatic refunds, but limited cash compensation

The US does not have a EU-style cash-compensation law for delays. What it has — strengthened by US DOT rules that took effect in 2024 — is a strong, automatic refund right.

• If your flight is cancelled or significantly changed (and you don't accept the rebooking), the airline must automatically refund the full fare to your original payment method. "Significant" generally means a delay of 3+ hours domestic / 6+ hours international, or a major schedule/airport change.
• Refunds must be prompt — typically within 7 business days for credit-card purchases.
• No automatic cash compensation for delays. Unlike the EU, a delayed-but-still-operating US flight doesn't owe you a payout. What you can get: rebooking, and for controllable delays, many US carriers now commit to meals and hotels per their own published customer-service plans.
• Tarmac delays and bumping are separate. Involuntary denied boarding (overbooking) does carry mandatory cash compensation under US rules — up to $2,150 depending on the length of the delay to your destination.

How to claim (US): for a cancellation refund, you usually don't have to do anything — it's automatic. If it doesn't arrive, request it in writing through the airline's site and cite the US DOT refund rule. For denied-boarding compensation, ask for the cash payment at the gate; don't accept only a travel voucher unless you want one.

The UK/EU regime: real cash for delays

UK261 (the retained UK version of EU Regulation 261/2004) and EU261 are far more generous on delays — this is what UK readers and anyone flying from the UK/EU should know cold.

You're covered when: you depart from a UK/EU airport on any airline, or you arrive in the UK/EU on a UK/EU airline. Compensation applies when the disruption is the airline's fault (not "extraordinary circumstances" like severe weather or air-traffic-control strikes).

Distance	Delay at arrival	EU261 amount	UK261 amount
Up to 1,500 km	3+ hours	€250	£220
1,500–3,500 km	3+ hours	€400	£350
Over 3,500 km	3–4 hours	€300 (50%)	£260 (50%)
Over 3,500 km	4+ hours	€600	£520

On top of the cash, you're owed care (meals, phone calls, and a hotel if you're stuck overnight) and a choice between a refund or re-routing when a flight is cancelled. Compensation is per passenger, including children on a paid seat.

How to claim (UK/EU): keep your boarding pass and any delay confirmation, then submit a claim directly through the airline's website — look for "EU261 / UK261 claim" or "flight disruption." If the airline refuses or stalls, escalate: in the UK to the CAA or an alternative dispute resolution body; in the EU to the relevant national enforcement body. You generally have up to six years to claim in the UK, so old disrupted flights may still be claimable. Avoid claim-farm companies that take 25–40% — direct claims are free and not much harder.

The one rule that catches everyone out

Compensation (the EU/UK payout) is separate from a refund (your fare back). You can be owed both: if a flight is cancelled, you get your money back and, if it qualifies, the UK261/EU261 cash on top. Airlines often quietly offer only a voucher or a rebooking and hope you don't ask for the rest. Always ask for what you're owed in cash.

A realistic worked example

Your London–Athens easyJet flight (about 2,400 km) is delayed 4 hours because of a crew shortage — that's within the airline's control. Under UK261 you're owed £350 per passenger, plus meal vouchers during the wait. A family of four: £1,400. The flight still operated, so there's no refund — but the compensation alone covers the trip. Most of that family will never claim it unless someone tells them to.

The 2026 angle

US DOT's automatic-refund rule is the biggest consumer-protection shift in years, and it's fully in force in 2026 — airlines can no longer push you into a voucher when they cancel. The UK/EU 261 framework is unchanged and remains the strongest delay-compensation regime in the world. The trap is the same in both markets: the money is yours, but you usually have to know to ask. Before you book, also check who sold you the ticket, because refunds route back through the seller — see book direct vs through an OTA.

The best disruption insurance is not getting overcharged in the first place. Flyozo alerts you to fare drops of 30–80% across American, Delta, United, BA, Virgin and the LCCs, so you book at the lowest real price — and if the airline then cancels or delays, you know exactly what it owes you. Premium runs about $24 a year; a single claimed UK261 payout pays for two decades of it.
