How to Prove Your Flight Was Delayed 3+ Hours

The three-hour threshold is the gateway to EC261 delay compensation, and it is also the point at which airlines are most likely to dispute your claim. Airlines have their own records of arrival times, and those records do not always match reality, sometimes due to how they measure arrival, sometimes for less innocent reasons. Having your own evidence of when you actually arrived makes your claim significantly harder to dismiss.

What "arrival" legally means

The Court of Justice of the European Union ruled in 2014 that arrival time is the moment when at least one aircraft door is opened at the gate, on the presumption that passengers are then permitted to leave. It is not when the wheels touch the runway, not when the aircraft reaches the stand, and not when you walk into the terminal.

This distinction matters because taxiing from the runway to the gate can take 15 to 20 minutes at large airports. An airline that records arrival as "wheels down" at 16:55 may claim a delay of only 2 hours 55 minutes, when the doors did not open until 17:12, making the actual delay 3 hours 12 minutes and your claim valid.

Evidence to collect during the disruption

Evidence to gather after the fact

Flight tracking services. Websites like Flightradar24, FlightAware, and FlightStats record actual departure and arrival times for virtually every commercial flight. These records come from independent ADS-B data (transponder signals from the aircraft itself), making them credible third-party evidence. Note that they typically record landing time, not door-opening time. Add a reasonable buffer of 10 to 15 minutes for taxiing and door opening.

Airport records. Airports maintain detailed records of aircraft movements, including gate arrival times. In escalation proceedings or court cases, these records can be requested. They are considered highly reliable evidence.

Borderline cases

For delays close to the three-hour mark — between 2 hours 45 minutes and 3 hours 15 minutes — every piece of evidence matters. Airlines will argue for the shorter figure; you should present the strongest case for the accurate one. Multiple sources of evidence (a flight tracker screenshot plus a timestamped departure board photo plus a post-landing transport receipt) create a much stronger case than any single piece alone.

Remember: your delay is measured against the scheduled arrival time on your original booking, not the departure delay. A flight that departs two hours late but makes up time in the air may arrive less than three hours late. Conversely, a flight that departs only 90 minutes late but encounters headwinds may arrive more than three hours behind schedule.
