UK261 After Brexit: How the Rule Changed and What It Means Now

UK261 post-Brexit changes have been in effect since 31 January 2020. The legal instrument is the Air Passenger Rights and Air Travel Organisers Licensing (Amendment) (EU Exit) Regulations 2019, which retained EU261/2004 in UK domestic law with modifications appropriate for a non-EU state. UK261 applies to: (a) flights departing from a UK airport (regardless of carrier nationality), and (b) flights arriving in the UK on a UK carrier or a carrier licensed by the UK Civil Aviation Authority. The substantive passenger rights (right to compensation for long delays and cancellations, right to care, right to re-routing) are essentially unchanged from EU261. The main changes are in enforcement structure, jurisdictional scope, and the interpretation authority. See EU261 rights in detail for the EU framework the UK rule derived from.

UK261 applies to departures from UK airports on any carrier. It also applies to arrivals into the UK on UK-licensed carriers. EU261 applies separately to EU departures and EU-licensed carrier arrivals in the EU. A UK-EU flight may trigger both regimes on different legs.

The substantive passenger entitlements under UK261 are identical to EU261 as it stood at the moment of Brexit. The triggering conditions are the same: cancellations with less than 14 days' notice, delays of 3 hours or more on arrival, and denied boarding. The right to care obligations (meals, refreshments, accommodation for overnight delays, two telephone calls) are identical. The right to re-routing at the earliest opportunity or at a later date of the passenger's choosing is identical. The extraordinary circumstances defence is preserved in identical language. The compensation tiers are converted to GBP at the fixed rates in the retained regulation. What the UK did not retain is the ongoing ability to benefit from CJEU case law developments after Brexit: UK courts interpret UK261 independently.

UK261 compensation amounts are fixed in GBP: GBP 220 for flights under 1,500 km, GBP 350 for intra-EU flights between 1,500 and 3,500 km (this category now refers to flights of equivalent distance from the UK), and GBP 520 for flights over 3,500 km. These are the GBP equivalents of the EUR 250, EUR 400, and EUR 600 amounts in EU261. The conversion was fixed at Brexit and has not been updated since. As of 2025, the EUR amounts are worth more in GBP at current exchange rates than the fixed GBP amounts, meaning EU261 passengers on the same route may receive more than UK261 passengers in absolute terms. For a long-haul delay, a UK passenger receives GBP 520 while an EU passenger receives EUR 600 (approximately GBP 510 to 520 at 2025 rates, roughly equivalent, but this changes with exchange rate movements).

The GBP amounts are fixed in the regulation. They are not adjusted for inflation or exchange rate changes. A review of the amounts would require a new statutory instrument.

Under EU261, enforcement is divided across 27 National Enforcement Bodies. Under UK261, enforcement is consolidated with the UK Civil Aviation Authority. The CAA's Passenger Advice and Complaints Team (PACT) handles UK261 complaints that passengers refer after exhausting the airline's complaints process. Unlike some EU NEBs (particularly those in Germany and the Netherlands), the CAA does not issue binding individual decisions: it applies pressure and can refer systemic non-compliance to its enforcement division. This means PACT is most effective as a compliance signal for systemic airline behaviour, not as a fast resolution mechanism for individual cases. For individual case resolution, the UK ADR scheme (CEDR or Aviation ADR) is the more powerful route, because ADR decisions are binding on airlines. The CAA passenger complaints page explains both routes.

PACT is the CAA's internal team that reviews UK261 complaints, not an ADR scheme itself. The UK ADR schemes for aviation are CEDR (Centre for Effective Dispute Resolution) and Aviation ADR, both approved by the CAA. Passengers who exhaust the airline's complaints process (receive a final response or have waited 8 weeks without resolution) can refer to the ADR scheme that the airline is a member of. ADR is free to passengers. The adjudicator's decision is binding on the airline but not on the passenger: if you disagree with the ADR decision, you can still pursue the matter in court. ADR decisions are typically issued within 90 days of case acceptance. Most major UK airlines are members of an approved ADR scheme, though membership is not mandatory. Non-member airlines can be referred to the CAA but not to ADR.

ADR is binding on the airline, not the passenger. If the ADR decision awards less than you believe you are owed, you can still take the matter to the small claims court.

Since Brexit, the CJEU has issued several decisions narrowing the extraordinary circumstances defence under EU261. UK courts are not bound by post-Brexit CJEU decisions. The UK position as of 2025 is: UK courts and ADR bodies continue to apply the same two-part test (not inherent to normal operations, beyond the airline's actual control) that CJEU case law established pre-Brexit. On technical faults, UK courts have generally followed the Wallentin-Hermann standard. On strikes, UK courts have applied a similar wildcat vs scheduled distinction. The divergence areas to watch are: (1) cascading delay cases where CJEU decisions have narrowed the extraordinary circumstances defence for flights downstream of an original extraordinary event, and (2) crew rest cases where CJEU has been more restrictive than UK tribunals. Practically, for most cases, UK261 and EU261 produce the same outcome on extraordinary circumstances defences. See EU261 extraordinary circumstances 2025 case law for the EU position in detail.

UK261 claims follow the same basic process as EU261 but through UK institutions. File directly with the airline first, referencing the specific UK261 right. If the airline refuses or does not respond within 8 weeks, refer to the ADR scheme (check which scheme the airline belongs to at the CAA website) or to PACT if the airline is not an ADR member. The limitation period for UK261 claims is 6 years under the Limitation Act 1980. TravelStacks handles UK261 claims via /claim on the same no-win no-fee basis as EU261 claims: 25% of recovered compensation, nothing if the claim does not succeed. For claims that have already been refused by the airline, TravelStacks files the ADR or PACT submission and handles all correspondence. See how long does flight refund take TravelStacks for UK261 timeline data.

UK261 has a 6-year limitation period. Do not assume a 2022 or 2023 delayed flight is out of time. Check the departure date and file before the window closes.
