EU261 vs US DOT: Which Rules Apply on Budget Transatlantic Flights

Quick decision: Flying from an EU or UK airport on any carrier: EU261 or UK261 applies to the outbound leg. Flying from a US airport on a US carrier (United, Delta, American): US DOT applies. Flying from a US airport on a European budget carrier (Norwegian, Norse, Level): US DOT applies on the outbound, EU261 applies on the return EU leg. Both rules can apply to the same round trip on different legs.

The key question for any transatlantic flight is not which airline you booked, but which airport you departed from and whether the operating carrier holds an EU/EEA operating license. These two variables determine everything.

• ›

  EU airport departure on any carrier: EU261 applies regardless of the airline's nationality.

• ›

  US airport departure on a US carrier: US DOT rules apply. EU261 does not.

• ›

  US airport departure on an EU/EEA carrier: US DOT applies for that US-departing leg. EU261 applies if the same carrier brings you back from an EU airport.

• ›

  US airport departure on an EU carrier arriving at an EU airport (if you're returning): EU261 applies to the return leg.

EU261 covers all flights departing from EU member state airports, regardless of the airline's nationality. It also covers flights arriving at EU airports if operated by an EU or EEA-licensed carrier. Both rules are relevant for transatlantic travel.

• ›

  Paris CDG to New York JFK on Air France: Covered outbound (EU departure, EU carrier) and not inbound under EU261 (US departure, but Air France is EU, so inbound IS covered at arrival in EU).

• ›

  New York JFK to Paris CDG on Delta: Not covered by EU261 (US departure, non-EU carrier). The return Paris to JFK on Delta IS covered (EU departure on any carrier).

• ›

  Oslo to New York on Norwegian Air Shuttle: Covered. Norway is EEA, Norwegian holds an EEA license, and Oslo is in the EEA. EU261 applies via the EEA extension.

• ›

  London Gatwick to New York on British Airways: UK261 applies (identical framework, GBP amounts).

For long-haul flights over 3,500 km, EU261 fixed compensation is €600 per passenger for delays of 3 or more hours at the final destination. This is the category that covers essentially all transatlantic routes. A family of four on a delayed Paris to New York flight is entitled to €2,400 in total if EU261 applies.

US DOT rules apply to all flights departing from US airports, regardless of carrier. The rules cover refund rights, involuntary denied boarding (IDB) compensation, and certain service standards.

• ›

  Refund right: If your transatlantic flight from a US airport is canceled or delayed 6+ hours and you choose not to travel, you are entitled to a full cash refund under DOT's final rule (effective October 2024).

• ›

  IDB compensation: If you are involuntarily denied boarding on a US-departing transatlantic flight, DOT IDB rules apply: up to $1,075 for delays under 4 hours, up to $2,150 for delays over 4 hours.

• ›

  Delay compensation: Unlike EU261, US DOT does not require fixed cash compensation for flight delays. Passengers who travel despite the delay receive no automatic cash payment under DOT rules for the delay itself.

• ›

  Tarmac delay rule: US airports enforce a 4-hour tarmac limit for international flights. This applies to all carriers at US airports.

The critical difference: EU261 pays fixed cash compensation for delays of 3+ hours even if you travel on the delayed flight. US DOT does not. A US passenger on a 5-hour-delayed transatlantic flight from JFK who still travels gets no cash compensation under DOT rules. The same passenger on the same delay from CDG would get €600 per person under EU261.

The financial difference between the two systems is significant for transatlantic passengers.

• ›

  EU261 delay compensation (3+ hours, transatlantic): €600 per person fixed. Not based on ticket price.

• ›

  US DOT delay compensation: Zero. No cash compensation for delays under DOT rules as of 2024 (DOT has proposed but not yet implemented delay compensation requirements).

• ›

  EU261 IDB: €600 per person (transatlantic routes over 3,500 km).

• ›

  US DOT IDB: 400% of one-way fare, up to $2,150. For a $200 one-way fare, that is $800, lower than EU261 on most transatlantic tickets.

• ›

  EU261 refund: Full ticket cost within 7 days if you choose not to travel.

• ›

  US DOT refund: Full ticket cost if you choose not to travel on a significantly delayed or canceled flight.

For most US transatlantic passengers, EU261 is the stronger framework if it applies. The fixed €600 compensation for a 3-hour delay is more generous than anything DOT currently requires for the delay itself.

EU261 has an extraordinary circumstances defense: airlines can avoid paying the fixed compensation if they prove the disruption was caused by circumstances outside their control that could not have been avoided even with all reasonable measures taken. US DOT has no equivalent blanket exemption from the refund right.

• ›

  EU261 extraordinary circumstances: Weather making flight unsafe, ATC strikes, security incidents, bird strikes. Routine technical faults are NOT extraordinary per EU Court of Justice rulings.

• ›

  US DOT: No extraordinary circumstances defense for the refund right. A canceled flight due to weather still triggers the cash refund right if the passenger chooses not to travel.

• ›

  Practical implication: EU261 delay compensation can be denied for a genuine weather event. US DOT refund rights cannot be denied regardless of cause.

The net result: for weather-related disruptions, US passengers on EU-departing flights may lose the €600 compensation but retain the refund right. Passengers on US-departing flights retain the refund right but were never entitled to the €600 fixed compensation anyway.

Both systems address what airlines must provide during a delay, but the obligations differ in important ways.

• ›

  EU261 duty of care (applies regardless of extraordinary circumstances): Meals and refreshments after 2 hours, hotel and transport for overnight delays, two free phone calls or emails.

• ›

  US DOT duty of care (controllable delays only): Airlines that signed the DOT customer commitment pledge provide meal vouchers for controllable delays of 3+ hours and hotel for controllable overnight delays. Weather delays do not trigger hotel obligations under DOT.

• ›

  Re-routing rights under EU261: Airlines must offer re-routing to your final destination at no extra cost, or a refund if you choose not to travel.

• ›

  Re-routing under US DOT: No mandatory re-routing obligation, but airlines generally rebook affected passengers as a matter of practice.

EU261 duty of care is unconditional. Even for genuine weather-caused disruptions where EU261 compensation does not apply, airlines must still provide meals and hotel. This right is frequently overlooked by passengers who hear 'extraordinary circumstances' and assume they have no claims at all.

The transatlantic budget carrier market has expanded and contracted significantly since 2015. Here is how EU261 and US DOT apply to the key carriers.

• ›

  Norwegian Air Shuttle (DY): Norwegian Air Shuttle AS is a Norwegian carrier. Norway is EEA, so EU261 applies via the EEA extension to all Norwegian Air Shuttle flights from EEA airports.

• ›

  Norse Atlantic Airways (N0): Also a Norwegian carrier in the EEA. EU261 applies to Norse flights from EU/EEA airports.

• ›

  Level (LV): Operated by Iberia or Vueling, both EU carriers. EU261 applies to all Level flights from EU airports.

• ›

  Condor (DE): German carrier, EU261 applies.

• ›

  WOW Air: Defunct since 2019. A cautionary case study in airline insolvency.

• ›

  Play Airlines (OG): Icelandic carrier, EEA member. EU261 applies via EEA extension.

For flights from US airports on these carriers, US DOT applies for that US-departing segment. For their EU or EEA-departing segments (typically the return flight), EU261 applies.

Norwegian Air provides the clearest illustration of how both systems operate simultaneously on a round-trip transatlantic itinerary.

A round trip booked with Norwegian from New York JFK to Oslo (OSL) and back creates two distinct regulatory segments. The JFK to OSL leg departs from the US: US DOT applies. If the outbound is canceled and you choose not to travel, you are entitled to a cash refund under DOT. If it is delayed and you travel anyway, DOT provides no additional cash compensation. The OSL to JFK return leg departs from Norway, which is EEA: EU261 applies. A 3-hour delay entitles you to €600 per person in fixed compensation.

Norwegian's 2020 insolvency and subsequent restructuring complicated outstanding EU261 claims, as explored in the companion post on airline insolvency. The lesson: on transatlantic budget carriers, always note which airport is departing and file claims under the applicable system for each leg separately.

In most disruption scenarios, only one regulatory system applies to a given leg because each leg has one departure airport. However, some situations create overlap:

• ›

  IDB at a US airport on an EU carrier: Both DOT IDB rules and EU261 IDB rules may technically apply. You cannot double-recover the same amount, but you can claim under whichever provides the higher amount. EU261 fixed IDB (€600 transatlantic) often exceeds DOT IDB (400% of one-way fare) for lower-priced tickets.

• ›

  Cancellation at a US airport: DOT refund rights apply. EU261 does not apply to a US departure on a non-EU carrier. On an EU carrier at a US airport, the refund right applies under DOT; EU261 applies to the EU-returning leg separately.

• ›

  Tarmac delay at a US airport: DOT's 4-hour international tarmac rule applies regardless of carrier nationality.

The practical rule: do not try to claim EU261 for a US-departing disruption. Focus EU261 claims on EU-departing legs and DOT claims on US-departing legs. For the IDB overlap, claim the higher amount and note in your claim which regulation you are relying on.

Time limits differ significantly between the two systems.

• ›

  EU261 time limits: Set by national law of the departure country. England and Wales: 6 years. France and Spain: 5 years. Germany and Austria: 3 years. Norway: 3 years under Norwegian law.

• ›

  US DOT claims: No statutory time limit for DOT complaints, but the DOT recommends filing within 1 to 2 years. Credit card chargeback windows are much shorter: typically 60 to 120 days from the statement date.

• ›

  Practical advice: File EU261 claims as soon as possible rather than relying on the long limitation periods. Evidence (FlightAware records, weather data) is easier to obtain close to the event.

For most transatlantic disruptions, EU261 is the stronger passenger protection framework. The fixed €600 compensation for a 3-hour delay is guaranteed regardless of ticket price, and the duty of care rights (meals, hotel) apply unconditionally even for weather delays. US DOT provides a robust refund right and strong IDB compensation, but offers nothing equivalent to EU261's fixed delay compensation.

However, US DOT has two advantages over EU261 in specific scenarios: the refund right cannot be defeated by an extraordinary circumstances defense, and the IDB payout (400% of fare, up to $2,150) can exceed EU261's €600 for passengers with expensive tickets.

For US passengers planning transatlantic trips, the practical implication is: when possible, book itineraries where the flight departs from an EU or EEA airport on an EU or EEA carrier for the maximum return leg, securing EU261 rights on the way home. Or use TravelStacks to handle the claim whichever system applies.

• ›

  Do not claim EU261 for a US-departing leg on a non-EU carrier. The regulation simply does not apply. Filing under EU261 when DOT is the applicable rule will result in a denial and waste time.

• ›

  Do not assume DOT requires cash compensation for delays. Unlike EU261, DOT does not currently require fixed cash payments for delays. Your DOT right is a refund if you choose not to travel.

• ›

  Do not confuse the arrival delay rule with the departure delay rule. EU261 compensation is triggered by 3-hour arrival delay at the final destination, not departure delay. A 3.5-hour departure delay partially recovered in flight may result in only a 2.5-hour arrival delay, which does not qualify.

• ›

  Do not accept a voucher from a transatlantic carrier without requesting cash explicitly. Both EU261 and DOT require airlines to offer cash refunds. Accepting a voucher waives your cash right unless consent was uninformed.

• ›

  Do not miss the credit card chargeback window. For DOT refund violations, the chargeback window (60 to 120 days from the statement) closes much faster than any regulatory process.

Q: I flew Norwegian from New York to Oslo. The return was delayed 4 hours. Which rule applies?

EU261 applies to the Oslo to New York return leg because it departed from Norway, which is in the EEA. A 4-hour arrival delay entitles you to €600 per person in EU261 compensation, assuming the airline cannot prove extraordinary circumstances.

Q: My flight from JFK to London on British Airways was canceled. Which rules apply?

US DOT applies for the JFK-departing leg: you are entitled to a cash refund if you choose not to travel. UK261 does not apply to a US departure. However, if you rebooked and the return LHR to JFK leg is later disrupted, UK261 applies to that return.

Q: Can I get both EU261 compensation and a DOT refund for the same flight?

Only if the flight genuinely triggers both frameworks, which is rare for a single leg. More commonly, a round trip creates one leg under each system. You can claim under each system for the applicable leg. You cannot double-recover the same amount under both systems.

Q: Norse Atlantic delayed my London to New York flight 3.5 hours. I still traveled. Am I owed anything?

Yes, under UK261 (London is a UK departure). A 3.5-hour arrival delay on a transatlantic route entitles you to £520 per person (the UK equivalent of €600). File a UK261 claim against Norse Atlantic citing UK261.

Q: Level canceled my Paris to New York flight. What can I claim?

EU261 applies: Paris is an EU departure. You are entitled to €600 per person in fixed compensation (transatlantic distance over 3,500 km) plus a cash refund of your ticket if you choose not to travel on the rebooked flight.

Q: What is the DOT weather rule for transatlantic cancellations?

Under US DOT rules, weather does not affect your cash refund right for a canceled or 6+ hour delayed international flight from a US airport. You are entitled to a full cash refund regardless of the cause. Weather does affect hotel obligation: airlines with DOT commitments only provide hotel for controllable delays, not weather.

Q: I was denied boarding on a Norse Atlantic flight from New York. Which rules apply?

US DOT IDB rules apply (New York is a US departure). You are entitled to 200% of the one-way fare (up to $1,075) if rebooked within 4 hours, or 400% (up to $2,150) if rebooked later. EU261 IDB rules do not apply to US-departing flights on non-EU carriers.

Q: How long do I have to file an EU261 claim for a Norwegian transatlantic disruption?

Norwegian flights typically depart from Norway (Oslo, Bergen) or Sweden. Norway uses a 3-year limitation period under Norwegian law. For Norwegian Air International (Irish-licensed subsidiary), Irish law (6 years) may apply. File sooner rather than later to preserve evidence.

Q: EU261 said my delay does not qualify because it was weather. Do I still get a refund?

Yes. The extraordinary circumstances defense eliminates the fixed €600 compensation but not the Article 8 refund right. If you chose not to travel on the delayed or canceled flight, you are entitled to a full ticket refund regardless of the weather classification.

Q: I want to claim for a Condor transatlantic delay. Which NEB do I use?

Condor is a German carrier. File with the German NEB (Luftfahrt-Bundesamt, LBA) for flights departing Germany, or with the NEB of whatever EU country the flight departed from.
