How to Prove Flight Delay Time for a UK261 Claim (2026)

By Emma Walsh 9 min read
Quick Answer

UK261 measures delay when at least one aircraft door opens at your final destination — not wheels-down, not gate assignment, not departure time. Document scheduled vs actual arrival using airline apps, email confirmations, boarding passes, and third-party trackers (FlightRadar24, FlightAware). For connecting itineraries on one booking, measure delay at the last airport. Screenshot everything the same day — airlines rarely dispute timestamped app data paired with boarding passes.

The arrival-time rule — where airlines hide deniability

The three-hour UK261 compensation threshold applies to arrival delay at your final destination on the ticket. A flight that departed five hours late but made up time crossing the Atlantic and landed two hours 59 minutes behind schedule does not qualify — even if you sat on the tarmac for hours at departure.

A flight that departed five hours late but made up time crossing the Atlantic and landed two hours 59 minutes behind schedule does not qualify — even if you sat on the tarmac for hours at departure.

Arrival time is defined as when at least one door of the aircraft opens to disembark passengers — not when the plane touches down or reaches the gate. In practice, airline app "arrived" timestamps and baggage-hall entry times approximate this moment closely enough for claims.

Airlines internal logs are authoritative in disputes — but they rarely contradict their own app data published to passengers. Screenshot your app's arrival notification and the flight status page on the day of travel.

Evidence to collect before leaving the airport

Boarding passes (paper or mobile) showing flight number, date, and booking reference. Booking confirmation email with scheduled departure and arrival times. Photos of departure boards showing delayed status and revised times — include the airport clock in frame if possible.

Airline app push notifications for delay updates and final arrival. Email delay notices from the airline — carriers often send "your flight is delayed" messages that help establish when they acknowledged the disruption.

If staff announce a reason, note it or ask for written confirmation — "technical fault" vs "weather" affects compensation eligibility. A photo of a handwritten delay voucher or hotel chit can document the airline's acceptance of responsibility.

Using flight trackers after the event

FlightRadar24 and FlightAware archive historical flights with gate and runway timestamps. Search your flight number and date; export or screenshot the landing and on-block times. These services are widely accepted in ADR proceedings when airline records are ambiguous.

Official airport websites sometimes publish arrival tables — Heathrow, Gatwick, and Manchester archive recent arrivals. Cross-reference tracker data with airport records for stronger evidence.

For old claims (up to six years in England and Wales), trackers may still hold data — search early before archives purge. Your email inbox may retain booking confirmations years back.

Connecting flights and multi-leg bookings

Single booking (one PNR): measure delay at the final destination airport on the last flight. If Manchester–Heathrow–New York was booked together and you arrived JFK 4+ hours late because the Manchester leg was delayed, the operating carrier on the delayed segment owes compensation based on total distance and final arrival delay — even if the transatlantic leg itself departed on time.

Separate tickets: each flight stands alone. A delay on ticket one that causes you to miss ticket two does not create UK261 liability on the second airline unless that second flight was also delayed 3+ hours on its own. See /guides/flight-delay-missed-connection-codeshare-uk-2026 for self-transfer pitfalls.

Codeshare: claim against the operating carrier (whose logo is on the aircraft), not the marketing airline on your ticket — unless they are the same company. BA-marketed flights on American metal from the US to London fall outside UK261 entirely because American is neither UK nor EU.

Sample claim wording — what to put in the form

Subject line: UK261 Compensation Claim — [Flight Number] [Date] [Route]. Opening line: "I am claiming fixed compensation under The Air Passenger Rights and Air Travel Organisers' Licensing (Amendment) (EU Exit) Regulations 2019 (UK261) for flight [number] on [date] from [origin] to [destination]."

Subject line: UK261 Compensation Claim — [Flight Number] [Date] [Route]. Opening line: "I am claiming fixed compensation under The Air Passenger Rights and Air Travel Organisers' Licensing (Amendment) (EU Exit) Regulations 2019 (UK261) for flight [number] on [date] from [origin] to [destination]."

State scheduled arrival: [time]. Actual arrival (door open): [time]. Delay at final destination: [X hours Y minutes]. Flight distance: [km] — compensation tier claimed: £[amount] per passenger under Article 7.

List all passengers with names as on boarding passes. Attach evidence listed above. State: "The delay was not caused by extraordinary circumstances" unless you know the airline's stated reason — in which case rebut it specifically. Request payment by bank transfer within 28 days.

Frequently Asked Questions

Does the delay clock start at departure or arrival?

Arrival at final destination for compensation. Departure delay matters only for duty-of-care meal and hotel thresholds — see /guides/flight-delay-duty-of-care-reimbursement-uk-2026.

Is FlightRadar24 evidence accepted by airlines?

Yes, routinely in ADR and direct claims — especially when paired with boarding passes and airline app screenshots. It is not legally binding but highly persuasive.

Can I claim without boarding passes?

Often yes — booking reference and e-ticket plus tracker data can suffice. Boarding passes speed processing and prove you travelled.

What counts as final destination on a connection?

The last airport on your single-booking itinerary — not intermediate stops. Measure door-open time there.

How do I calculate flight distance for UK261 tiers?

Great-circle distance between origin and final destination airports — use any reputable flight-distance calculator. Under 1,500 km = £220 tier; 1,500–3,500 km = £350; over 3,500 km = £260 or £520 depending on 3–4 vs 4+ hour arrival delay.
