Which rules cover LHR–PRG
London → Prague
Whatever the airline, this direction is covered by UK261 (the flight departs from the UK (Article 3(1)(a)), whatever the airline). On an EU airline it is also under EU261. If the airline refuses, the complaint goes to the airline's dispute scheme or the UK CAA for UK261 or Civil Aviation Authority for EU261 (the flight arrives in Czechia from outside the EU).
Prague → London
Whatever the airline, this direction is covered by EU261 (the flight departs from the EU (Article 3(1)(a)), whatever the airline). On an EU airline or a UK airline it is also under UK261. If the airline refuses, the complaint goes to Civil Aviation Authority for EU261 (the flight leaves Czechia) or the airline's dispute scheme or the UK CAA for UK261.
Because both EU and UK rules can reach this route, a passenger may find two rules covering the same trip. Each excludes people already compensated under the other's law for the same event, so the claim is made once, under whichever the airline accepts — in money terms €250 or £220.
What you could be owed by hours late
Arrival delay at PRG (or LHR on the return), for a delay caused by the airline, per passenger, where each rule applies:
| Hours late | EU261 | UK261 |
|---|---|---|
| 2 hours | €0 | £0 |
| 3 h 30 min | €250 | £220 |
| 4 h 30 min | €250 | £220 |
| 6 h 30 min | €250 | £220 |
| 9 h 30 min | €250 | £220 |
At 1,044 km the amount is the same from 3 hours late onwards — there is no extra for longer delays under the EU and UK rules.
How London LHR runs
The UK Civil Aviation Authority's figures for 2025 show 76.7% of flights at London Heathrow Airport running early or no more than 15 minutes late, against 67.3% in 2024, with an average delay of 12.8 minutes (18 in 2024). 4.2% were more than an hour late and 0.49% more than three hours — the length of delay at which UK261 starts — and 6,376 flights (1.32%) were cancelled. These are all flights at the airport, arrivals and departures, not this route alone.
The distance and the band
EU261 and UK261 measure distance "by the great circle route method" between the departure airport and the final destination. From the published coordinates of London Heathrow Airport (51.470748, -0.459909) and Václav Havel Airport Prague (50.100874, 14.259911) that is 1,044 km. The nearest band boundary is 1,500 km, 456 km beyond this route, so the band is not in doubt. Among the 84 routes on this site in the up to 1,500 km band, it is number 26 by length.

If LHR–PRG is only one leg of your booking, measure to the final destination instead: a connection that makes you late at the end is compensated over the whole journey's distance.
If the flight is cancelled
Cancelled with less than 14 days' notice and re-routed to arrive 6 hours late, an EU261 passenger is owed €250 here. If the replacement left within the allowed early margin and landed within the re-routing window, nothing is owed; if it landed within 2 hours but outside those windows, the airline may pay half — €125. On a cancellation you may instead take a refund within 7 days.
Help at the airport while you wait
On a flight of this length, meals and refreshments are owed once the departure is 2 hours late under EU261 and UK261, and a hotel with transport if you have to stay overnight — whatever caused the delay. Keep receipts for anything you buy: it is claimed back separately from any compensation.
Claiming on this route
Claim from the operating airline directly — it costs nothing.
UK261: If the airline's final answer is unsatisfactory, or it has not answered within eight weeks, go to the alternative dispute resolution (ADR) body the airline belongs to, or to the CAA's Passenger Advice and Complaints Team if it belongs to none.
EU261: If the airline does not reply within two months, or the reply is unsatisfactory, complain to the national enforcement body of the country where the incident happened.
