How to File a UK261 Claim Against a Non-UK Airline

Any carrier operating a flight departing from a UK airport is subject to UK261, regardless of nationality. If your Delta, United, Emirates, Air France, or any other non-UK carrier flight departs from London Heathrow, Manchester, Edinburgh, or another UK airport and arrives 3+ hours late, UK261 compensation applies.

This is one of the most important UK261 rules for travelers. The departure airport determines coverage, not the airline's home country. A Delta flight from Heathrow to New York that arrives 4 hours late at JFK triggers UK261 compensation of £520 per passenger, the same as a British Airways flight on the same route. Delta cannot invoke being a US carrier to avoid UK261 obligations on UK-departure flights.

For a non-UK airline, UK261 applies in one scenario: departing from a UK airport. (The second scenario, involving a UK carrier arriving in the UK from a non-UK airport, only applies to UK carriers, not non-UK airlines.)

• ›

  Delta LHR to JFK: COVERED. LHR is a UK airport. Any carrier departing LHR is subject to UK261.

• ›

  United MAN (Manchester) to EWR: COVERED. Manchester is a UK airport.

• ›

  Emirates LHR to DXB: COVERED. LHR departure.

• ›

  Air France LHR to CDG: COVERED. LHR departure.

• ›

  Delta JFK to LHR: NOT covered on JFK departure (Delta is not a UK carrier). UK261 only covers the LHR departure direction for non-UK airlines.

• ›

  US carriers with LHR/MAN departures: Delta, United, American Airlines, JetBlue (all operate from UK airports).

• ›

  Middle East carriers with LHR/MAN departures: Emirates, Qatar Airways, Etihad Airways.

• ›

  EU carriers with LHR departures: Air France, Lufthansa, KLM, Iberia (when operating from UK airports).

• ›

  Asian carriers: Singapore Airlines, Cathay Pacific, Japan Airlines (all operate from LHR).

• ›

  Any other airline: If the flight departs from any UK airport, UK261 applies regardless of the carrier's national origin.

1. 1

   Confirm your departure airport is in the UK. UK airports include all London airports (LHR, LGW, STN, LTN, LCY), Manchester (MAN), Edinburgh (EDI), Glasgow (GLA), Birmingham (BHX), Bristol (BRS), Newcastle (NCL), and others.

2. 2

   Calculate your compensation amount: Under 1,500 km = £220. 1,500 to 3,500 km = £350. Over 3,500 km = £520.

3. 3

   Write to the airline's customer service. Cite the UK Air Passenger Rights Regulation (the retained EU law as amended by the Air Passenger Rights and Air Travel Organisers Licencing (Amendment) (EU Exit) Regulations 2019). State the specific amount and basis.

4. 4

   Include your evidence: Boarding pass and flight status screenshot showing the delay at the final destination.

5. 5

   Wait up to 8 weeks for a formal response.

Non-UK airlines sometimes contest UK261 claims by arguing that UK261 does not apply to them. This argument fails: the regulation explicitly covers all carriers on UK-departure flights. If the airline refuses with this or any other reason, escalate through the official UK channels.

• ›

  Escalate to ADR: The airline must participate in an approved ADR scheme in the UK. Check whether the airline is a member of CEDR (cedr.com/aviation) or Aviation ADR (aviationadr.org.uk).

• ›

  File in MCOL: If ADR is not available for this airline or ADR fails, file in UK Small Claims Court at gov.uk/make-court-claim-for-money. UK courts have jurisdiction over non-UK carriers operating UK routes.

• ›

  Report to the UK CAA: The Civil Aviation Authority can investigate and take systemic action against non-UK carriers that repeatedly refuse to comply with UK261.

Not all non-UK airlines are members of CEDR or Aviation ADR. Check the CAA's website for the list of approved ADR members. If the airline is not a member of an approved ADR scheme, you can report this to the CAA, but your primary recourse for individual resolution is UK Small Claims Court.

• ›

  CEDR: cedr.com/aviation. Free for passengers. Check if the airline is a CEDR member.

• ›

  Aviation ADR: aviationadr.org.uk. Free for passengers. Check membership.

• ›

  CAA complaint: caa.co.uk for reporting systemic non-compliance.

• ›

  MCOL (small claims court): For any UK261 claim where ADR is unavailable or unsuccessful.

UK Small Claims Court (MCOL, Money Claim Online) is a highly effective venue for UK261 claims against non-UK airlines. Airlines operating in the UK are subject to UK court jurisdiction for matters arising from UK-departure flights. Filing fee is typically £25 to £115, recoverable if you win. Most claims settle before a court hearing.
