What is the main difference between US DOT rules and EU261?

The core difference is cash compensation. EU261 entitles passengers to fixed payments of €250 to €600 when flights arrive 3 or more hours late, regardless of what the money is for. US DOT rules do not require any cash payment for a delay. They only require a full refund if you choose not to travel due to a significant delay (3+ hours domestic, 6+ hours international), plus meals and hotels for controllable delays.

Does bad weather cancel my EU261 or UK261 rights?

Weather can eliminate the cash compensation portion of EU261 and UK261 if the airline can prove it was an "extraordinary circumstance" outside their control. However, your duty of care rights (meals, hotels, rebooking) remain intact regardless of the cause. Airlines sometimes incorrectly invoke weather to avoid paying compensation, so if the delay involved any controllable factor such as a late incoming aircraft, the compensation obligation may still apply.

How do I claim meals and hotel accommodation from an airline?

First, ask the gate agent or airline staff directly at the airport. Under EU261 and UK261 this is a legal obligation and most airlines will comply. If staff are unhelpful, purchase food and accommodation yourself, keep all receipts, and submit an expense claim to the airline in writing after your trip. In the US, duty of care only applies for controllable delays, so include documentation showing the delay was mechanical or crew-related rather than weather.

What happens if my plane sits on the tarmac for more than 3 hours?

Under US DOT rules, domestic carriers must give passengers the opportunity to deplane after 3 hours on the tarmac (4 hours for international flights), unless safety or air traffic control conditions prevent it. The airline must also provide food, water, and working lavatories after 2 hours. Violations can result in fines of up to $27,500 per passenger. You should document the time and file a complaint with the DOT if the rule is violated.

What is the exact delay threshold that triggers EU261 compensation?

EU261 compensation is triggered when you arrive at your final destination 3 or more hours later than the scheduled arrival time. The clock runs from when the aircraft doors open at your destination, not from when the plane pushes back or takes off. If a flight departs 5 hours late but makes up time in the air and lands only 2 hours 55 minutes late, compensation is not owed.

Can the airline offer me a voucher instead of a cash refund?

Airlines often push vouchers because they prefer to keep your money in their system. Under the DOT's 2024 refund rule, you are entitled to a cash refund to your original payment method for a significant delay, and you do not have to accept a voucher. Under EU261 and UK261, the fixed compensation must be paid in cash (bank transfer or check). You can voluntarily accept a voucher if you want, but you are never required to.

What can I do if the airline refuses to pay EU261 compensation?

If the airline rejects your claim or stops responding, you can escalate to a National Enforcement Body (NEB) in the relevant EU country, or to the Civil Aviation Authority in the UK. These are free government bodies that can investigate and enforce your rights. Many passengers also use a claims management service, which handles the process on a no-win-no-fee basis. Keep all boarding passes, booking confirmations, and written communications before escalating.

I live in the US. Can I still claim EU261 compensation?

Yes. Your country of residence is irrelevant. EU261 applies based on the flight route and the airline, not where you live. If you flew from London to New York on British Airways and arrived more than 3 hours late, you may qualify for UK261 compensation. If you flew from Paris to Chicago on Air France and arrived over 3 hours late, EU261 may apply. What matters is whether the flight departed from an EU or UK airport, or arrived in the EU or UK on an EU or UK carrier.

What Airlines Actually Owe You When Your Flight Is Delayed

Loren Castillo

Founder, TravelStacks

US DOT rules, EU261, and UK261 each have different thresholds and payout amounts. Here is a plain-language breakdown of what you are entitled to and when.

What the US DOT Requires

The US Department of Transportation sets the baseline rules for domestic and international air travel originating in the United States. While these rules are less generous than European frameworks, they do give passengers enforceable rights when airlines fall short. The DOT defines a "significant delay" as 3 or more hours for domestic flights and 6 or more hours for international flights. Learn more on the US DOT passenger rights page.

Cash refunds are guaranteed. If your flight is significantly delayed and you choose not to travel, the DOT requires airlines to offer a full cash refund to your original payment method, not just a travel credit or voucher. This rule took effect in October 2024 under the DOT's final refund rule.

›
Significant domestic delay: 3+ hours from scheduled departure.
›
Significant international delay: 6+ hours from scheduled departure.
›
Refund right: Full cash refund if you choose not to fly due to a significant delay.
›
Meals and hotels: Required only for controllable delays (mechanical issues, crew problems) -- not weather or air traffic control.
›
More detail: The DOT's consumer guidance is published at transportation.gov/airconsumer.

EU261: Up to €600 in Compensation

EU Regulation 261/2004 is the gold standard for air passenger rights worldwide. It applies to all flights departing from an EU airport, and to flights arriving in the EU on an EU-based carrier. The regulation is published in full at eur-lex.europa.eu. If your flight qualifies, you may be owed fixed cash compensation on top of any refund or rebooking. For a full walkthrough, see our EU261 compensation guide and the EU261 rights page.

1
Under 1,500 km: €250 per passenger for delays of 3+ hours at arrival.
2
1,500 to 3,500 km: €400 per passenger for delays of 3+ hours at arrival.
3
Over 3,500 km (intra-EU over 1,500 km): €600 per passenger for delays of 3+ hours at arrival.
4
Long-haul, short delay: If a flight over 3,500 km arrives 3 to 4 hours late, the airline may reduce compensation by 50% to €300.

The 3-hour rule applies to arrival, not departure. Your clock runs from when the aircraft door opens at your destination, not from when you pushed back from the gate. A flight that departs 4 hours late but lands only 2 hours 50 minutes late does not qualify for compensation.

UK261: The Post-Brexit Framework

After Brexit, the United Kingdom retained the core structure of EU261 and incorporated it into domestic law as UK Regulation 261. The rules apply to flights departing from a UK airport, or arriving in the UK on a UK-based carrier. Full details are on the UK261 rights page.

›
Compensation amounts: Identical tiers to EU261, but denominated in GBP (£220, £350, and £520 respectively).
›
Distance thresholds: Same 1,500 km and 3,500 km breakpoints as EU261.
›
Arrival threshold: Same 3-hour arrival delay trigger.
›
Claim window: UK law gives you 6 years to file a claim, compared to varying limitation periods across EU member states.
›
Carrier coverage: Applies to all airlines on UK-departing flights, and to UK carriers (such as British Airways and easyJet) on flights arriving in the UK.

Six years is a long window. If you have old travel records showing a qualifying delay, it is worth checking whether your claim is still within the UK261 limitation period. Many passengers leave money on the table simply because they did not realize they could file years later.

Duty of Care: Meals, Hotels, and Rebooking

Separate from cash compensation, airlines have a "duty of care" obligation when delays stretch for hours. Under EU261 and UK261 this duty is legally mandated. In the US, it applies only when the delay is within the airline's control (not weather or ATC). If your airline refuses to provide these basics, document everything and check your US DOT rights or EU261 rights to escalate.

1
Meals and refreshments: Airlines must provide food and drink vouchers proportional to the wait, typically triggered after 2 hours for short-haul under EU261.
2
Hotel accommodation: If an overnight stay becomes necessary, the airline must provide a hotel and transport to and from the airport.
3
Communication: Two free phone calls, emails, or faxes must be offered under EU261.
4
Rebooking: You are entitled to be rebooked on the next available flight at no extra cost, or on a later date of your choosing.
5
Refund option: If you no longer wish to travel, you can take a full refund instead of rebooking (EU261, UK261, and US DOT for significant delays).

Keep every receipt. If the airline fails to provide meals or a hotel, you can claim reasonable out-of-pocket expenses back. Take photos of departure boards, keep boarding passes, and save all food and hotel receipts. See our guide on how to get a refund from an airline for documentation tips.

Tarmac Delays: The 3-Hour Domestic / 4-Hour International Rule

A separate DOT rule addresses the specific nightmare of being trapped on a plane that cannot depart. The tarmac delay rule requires US carriers to offer passengers the opportunity to deplane before specific time limits are reached. This rule applies at US airports regardless of where the flight is going.

›
Domestic flights: Airlines must allow deplaning after 3 hours on the tarmac.
›
International flights: The limit is 4 hours.
›
Exceptions: The captain may delay deplaning if air traffic control or safety conditions make it unsafe or infeasible.
›
Amenities: Food, water, working lavatories, and medical attention must be provided after 2 hours on the tarmac.
›
Foreign carriers: Non-US airlines operating at US airports are subject to a 4-hour tarmac limit on all flights.

Violations carry heavy fines. Airlines face fines of up to $27,500 per passenger per violation of the tarmac delay rule. This is one of the few areas where US passenger rights have real teeth. If your airline violated this rule, file a complaint at transportation.gov/airconsumer.

What You Are Not Owed (US Domestic Flights)

This is the biggest misconception in US air travel. Many passengers believe they are owed cash compensation for a delayed domestic flight, similar to what EU261 provides in Europe. They are not. The US has no fixed cash compensation scheme for delays on domestic routes. The DOT framework gives you refund rights and (for controllable delays) duty-of-care entitlements, but no automatic payment simply because your flight arrived late.

Common misconception clarified. If your Chicago to Los Angeles flight arrives 5 hours late due to a mechanical problem, you are entitled to meals and hotel accommodation while you wait, plus a full refund if you choose not to fly. You are NOT entitled to a fixed cash payment for the delay itself. Cash compensation for delays is a European and UK right, not an American one.

›
No automatic delay payment: US domestic delays do not trigger fixed cash compensation under any current DOT rule.
›
Vouchers are not required: Airlines may offer travel credits voluntarily, but you can always decline and request a cash refund for a significant delay instead.
›
Trip interruption insurance: If you purchased travel insurance, your policy may cover delay-related costs the airline will not.
›
Credit card protections: Many premium travel credit cards include trip delay reimbursement. Check your card benefits.
›
Where EU/UK rules might still apply: If your delayed US departure was on an EU carrier (such as Lufthansa or Air France), EU261 may still apply for the outbound leg. See our EU261 rights page.
