UK261 and EU261 are near-twin regulations that protect air passengers on flights departing from, or arriving in, Europe and the United Kingdom. The UK version was carried over from EU Regulation 261/2004 when Britain left the European Union, so the core compensation amounts, delay thresholds, and duty-of-care rules are almost identical. The differences that matter are mostly about jurisdiction (which flights each law covers), who enforces the rules, deadlines for claiming, and some post-Brexit quirks around connecting flights. Understanding the UK261 vs EU261 differences can be the deciding factor in whether a claim succeeds and how much you receive, especially for flights operated by non-EU or non-UK carriers. This guide sets out exactly where the two regimes match, where they diverge, and what you should do if you are not sure which one applies to your disrupted flight. It is written as of September 2026 and reflects the rules as they stand today.

## The Direct Answer: What Is Different and What Is Not

The short answer is that for the overwhelming majority of passengers, UK261 and EU261 pay the same compensation, apply the same distance bands, and use the same delay thresholds. Compensation is fixed at £220 or €250 for short-haul flights up to 1,500 km, £350 or €400 for medium-haul flights between 1,500 km and 3,500 km, and £520 or €600 for long-haul flights over 3,500 km. On non-UK/non-EU carriers, short-haul intra-EU compensation drops to £175 or €125, and both regimes reduce long-haul payouts by 50% when a delay is under four hours on arrival.

The differences sit in four areas. First, jurisdiction: EU261 covers flights departing from any EU airport on any airline, plus flights arriving in the EU only when operated by an EU-licensed carrier. UK261 covers flights departing from the UK on any airline, plus flights arriving in the UK only on UK or EU carriers. Second, enforcement: EU261 is enforced by National Enforcement Bodies in each member state, while UK261 is enforced by the UK CAA, and unresolved complaints go to CEDR or AviationADR rather than national courts or ombudsmen in the EU. Third, time limits: the EU has no harmonised deadline, so national limitation periods range from one year (Belgium) to as much as six years (UK, England and Wales). Fourth, a legal divergence that emerged in 2023 in the UK around connecting itineraries booked as a single reservation, discussed below.

## Compensation Amounts: Effectively Identical

The payment tables are the same in substance, adjusted only for currency. A flight from London to Madrid (roughly 1,270 km) qualifies for £220 under UK261 or €250 under EU261 when delayed more than three hours at arrival, cancelled with less than 14 days' notice, or downgraded. A flight from Paris to New York (about 5,837 km) qualifies for the top band of €600 or £520. The distance is measured as great-circle distance between origin and final destination, not the flight path flown, and the measure is arrival delay, not departure delay. A flight that leaves four hours late but lands two hours late pays nothing under either law.

Both regimes apply the same reduction clause: if a long-haul flight is re-routed and arrives fewer than four hours late, or a medium/short-haul flight arrives fewer than three hours late, compensation is halved. So a Manchester to Dubai flight arriving three hours late pays £260 rather than £520 under UK261, exactly as an Amsterdam to Dubai flight would pay €300 rather than €600 under EU261. Downgrades work identically too: 30% of the ticket price refunded for flights over 3,500 km, 50% for shorter flights, payable within seven days. Duty of care also matches: after a two-hour short-haul or four-hour long-haul delay, the airline must provide meals, refreshments, and communication; for overnight delays it must cover hotel accommodation and transfers regardless of whether compensation is ultimately due.

## Jurisdiction: Where the Two Laws Stop and Start

Jurisdiction is the most practical difference between the two regimes, and it trips up passengers on transatlantic and Middle East routes more than any other group. EU261 applies to any flight departing from an airport in an EU member state, plus Norway, Iceland, and Switzerland under separate agreements, regardless of the airline's nationality. It applies to flights arriving into the EU only when the operating carrier is licensed in the EU, Norway, Iceland, or Switzerland. That means a delayed American Airlines flight from New York to Frankfurt pays nothing, but the same airline's Frankfurt to New York flight is fully covered.

UK261 mirrors that logic for the UK. Any flight departing from a UK airport is covered regardless of carrier, so a delayed Emirates flight leaving London Gatwick falls under UK261. Flights arriving into the UK are covered only when the carrier is a UK or EU airline. So Emirates from Dubai to Gatwick is not covered by either regime for the inbound leg, a genuine gap that catches many passengers. Conversely, a British Airways flight from Chicago to Heathrow is covered by UK261 for the inbound leg and would have been covered by EU261 before Brexit, since BA is an EU-licensed carrier. After 31 December 2020, the EU-licensed-carrier category shrank for UK arrivals, which is one of the quiet consequences of Brexit that passengers still discover the hard way.

| Feature | EU261 (Regulation 261/2004) | UK261 (The Air Passenger Rights Regulations) |
| --- | --- | --- |
| Departing flights covered | All flights departing EU/EFTA airports, any airline | All flights departing UK airports, any airline |
| Arriving flights covered | Only on EU/EFTA-licensed carriers | Only on UK or EU-licensed carriers |
| Compensation short-haul (under 1,500 km) | €250 (€125 non-EU carrier intra-EU) | £220 (£175 non-EU carrier intra-UK/EU) |
| Compensation long-haul (over 3,500 km) | €600 (€300 if under 4 hrs late) | £520 (£260 if under 4 hrs late) |
| Delay threshold | 3+ hours at arrival | 3+ hours at arrival |
| Cancellation notice | Under 14 days triggers compensation | Under 14 days triggers compensation |
| Enforcement body | National Enforcement Bodies per member state | UK CAA, with CEDR/AviationADR dispute resolution |
| Claim deadline | Varies by country (1 to 6 years typically) | 6 years (England, Wales, NI); 5 years (Scotland) |
| Connecting flights | Treats multi-sector tickets per 2016 case law on sole operating carrier | 2023 UK rulings give wider treatment to missed connections on single bookings |

## The Connecting Flights Split: A Genuine Legal Divergence
The most interesting substantive difference to emerge since Brexit concerns connecting flights booked as a single reservation. EU case law (notably the Court of Justice's 2016 ruling in the Wegener case) treats a multi-sector ticket as a single unit for compensation purposes: the relevant distance is origin to final destination, and the relevant delay is measured at the final destination. In 2023, the UK County Court in the matter known as TAP v Clarke, plus CAA guidance that followed, reached a similar but arguably wider position for UK261, confirming that where a passenger misses a connection due to a delay on the first leg, compensation is calculated on the entire journey distance and final arrival delay, even when different carriers operate different legs under one booking.

In practice this matters on hub routes. A passenger booked Lisbon to Los Angeles via London on a single ticket, delayed four hours at arrival in Los Angeles because of a missed connection, can claim £520 under UK261 rather than being assessed leg by leg. Under EU261 the same logic applies through the sole-operating-carrier principle, but some EU enforcement bodies and airlines still resist when the connecting carrier differs from the first-leg carrier. The practical takeaway is the same under both laws: always book connecting flights on a single reservation. Separate tickets provide no protection under either regime, because a missed self-connection is treated as your problem, not the airline's.

## Extraordinary Circumstances: Same Defence, Different Arguments

Both regimes use identical wording for the airline's main defence: no compensation is payable for cancellations or delays caused by extraordinary circumstances that could not have been avoided by all reasonable measures. Established categories include air traffic control restrictions, severe weather, security threats, and acts of sabotage or war. What counts is heavily litigated, and the case law is broadly shared between the two jurisdictions because UK courts relied on CJEU precedents for years. Technical defects are generally not extraordinary unless they reveal a hidden manufacturing fault; airline staff shortages, overbooking knock-on delays, and crew rotation problems never qualify. Recent geopolitical events, including airspace closures linked to the Middle East conflict, have been treated as extraordinary where flights were genuinely rerouted or cancelled, but airlines must still demonstrate the disruption was unavoidable on their specific route.

A useful example: a British Airways passenger publicly detailed winning compensation for a technical fault that the airline initially called an extraordinary circumstance, by requesting the aircraft's technical log through a Subject Access Request and showing the fault was a routine, recurring defect. That tactic works under both UK261 and EU261. What differs is the escalation path. Under EU261, an airline that refuses a valid claim typically faces action in the courts of the departure country or enforcement body intervention, which varies wildly in effectiveness between, say, Germany and Italy. Under UK261, the CAA's approved dispute resolution schemes, CEDR and AviationADR, handle unresolved complaints free of charge for passengers, and airlines that belong to these schemes must comply with their decisions. Many passengers find this route faster and cheaper than a small-claims court filing.

## Time Limits and Practical Steps for Claiming

One of the clearest UK261 vs EU261 differences is the deadline. In England, Wales, and Northern Ireland, the Limitation Act 1980 gives you six years from the flight date to bring a claim; in Scotland it is five years. Under EU261 there is no EU-wide deadline because the regulation is silent; instead, each member state applies its own limitation period. Belgium's is a punishing one year, France is five years, Spain is five years, Germany three years, Italy two years (with ongoing court disputes over whether the shorter period is lawful under EU law). If you are unsure which law applies, assume the shortest plausible deadline and act early. Evidence also degrades: boarding passes, delay notifications in the airline app, and photographs of departure boards all get harder to retrieve with time.

The claim process itself is the same shape under both regimes. Write to the airline's compensation department directly, quoting your booking reference, flight number, scheduled and actual arrival times, and the specific regulation you are relying on. Keep it factual, state the amount due, and give a response deadline of 14 to 30 days. If the airline denies the claim citing extraordinary circumstances, ask for specifics: the cause, the evidence, and what reasonable measures were taken. Second step under UK261 is the airline's ADR scheme; under EU261 it is the National Enforcement Body of the departure country. Services such as AI Flight Refunds can handle both UK261 and EU261 claims, including the EC 261/2004 text itself, Turkey's SHY regulation, and Canada's APPR, typically charging a success fee of 25% to 35% of the recovered amount with nothing payable if the claim fails. That cost is worth weighing against the weeks of correspondence a contested claim usually requires, particularly for cross-border EU claims where language and small-claims procedures add friction.

## Common Mistakes and When to Act

The most frequent errors are surprisingly consistent. Passengers claim for departure delay when only arrival delay counts, so a two-hour arrival delay after a four-hour ground hold pays nothing. They accept travel vouchers instead of cash compensation without realising vouchers are optional extras, never a replacement for statutory entitlements under either law. They miss the distinction between compensation and reimbursement: hotel, meals, and rebooking costs are recoverable under the duty-of-care provisions even when the airline successfully invokes extraordinary circumstances and owes zero fixed compensation. And they give up after the first template rejection, when airlines reject a large share of first claims as a matter of process. Another common mistake is claiming under the wrong law: for example, demanding EU261 for an American Airlines inbound flight to Frankfurt, when no compensation is owed under either regime for that leg, versus correctly claiming UK261 for the same airline's outbound flight from Heathrow.

Timing matters for a second reason: airlines sometimes argue limitation has expired, and courts take different views on when a claim is formally brought. Realistically, submit your claim within the first year. Keep every document from the disruption day, take a screenshot of the airline's own delay notification, and check the great-circle distance of your route before stating a compensation amount, because miscalculating the distance band is an easy way to give an airline grounds to reopen the file. If your flight departed a UK or EU airport on or after 1 January 2021 and you are within the limitation window, you can still claim today for disruptions going back to 2015 in the UK and generally three to five years in most EU states. The rights are strong; they simply require the correct legal label and a paper trail.

## Bottom Line

For compensation amounts, thresholds, and passenger rights during disruption, UK261 and EU261 are functionally interchangeable, and no passenger loses money by being covered by one rather than the other. The differences that actually change outcomes are jurisdictional coverage on inbound flights by non-UK/non-EU carriers, the enforcement and escalation route (CAA and ADR schemes versus national enforcement bodies), varying national claim deadlines, and how connecting itineraries are treated when carriers differ. Check the departure airport first, the operating carrier second, and the limitation period third, and you will know within two minutes which law applies to your claim and how to enforce it.

## Quick answers

### Does UK261 pay more than EU261?

No, the amounts are effectively identical once converted between pounds and euros. Short-haul is £220/€250, medium-haul £350/€400, and long-haul £520/€600, with the same 50% reduction for shorter-than-four-hour long-haul delays. Currency conversion means payouts fluctuate slightly against each other, but the entitlement is the same.

### Which law applies to my flight after Brexit?

The law of your departure airport. A flight leaving the UK is governed by UK261 and a flight leaving an EU airport by EU261, regardless of airline. For arrivals, UK261 covers UK or EU carriers flying into the UK, while EU261 covers EU-licensed carriers flying into the EU.

### Can I claim both UK261 and EU261 compensation for the same flight?

No, you can only claim once per disrupted flight under whichever regulation applies. Filing duplicate claims with the same airline typically leads to both being refused, and it can delay processing of the valid claim.

### How long do I have to make a claim?

In England, Wales, and Northern Ireland you have six years from the flight date, and in Scotland five years. Under EU261 the deadline depends on the country, ranging from one year in Belgium to five or six years elsewhere, so check the departure country's limitation period.

### Are connecting flights treated differently under UK261 and EU261?

Both treat a single booking as one journey for compensation purposes, measuring delay at the final destination. UK rulings in 2023 and CAA guidance confirmed passengers can claim on the whole route distance even with different carriers on one ticket, and EU case law reaches a similar result through the sole operating carrier principle.
