Heathrow is the United Kingdom's largest airport, handling around 80 million passengers a year across four terminals. Its two runways operate close to capacity, so a single morning thunderstorm or an air traffic restriction can ripple through the rest of the day. Most long-haul departures leave from Terminal 5 (British Airways) and Terminal 2 (Star Alliance).
If you departed from Heathrow, UK261 applies whatever airline you flew and whatever passport you hold: £220 to £520 per passenger once you land three or more hours late, plus a refund or re-routing if the flight was cancelled. Arriving flights are covered too when the operating carrier is a UK or EU airline; if you arrived from outside the UK on a carrier that is neither, UK261 does not apply. Long-haul routes over 3,500 km sit in the top £520 band, which is where most Heathrow claims land.
Heathrow publishes live disruption notices, but a claim needs the airline's version of events: ask at the ticket or transfer desk for the delay reason in writing before you leave the terminal. Keep your boarding pass and, if you waited more than two hours, the receipts for the meals and drinks the airline should have covered under its duty of care. Note the actual arrival time at the gate rather than the scheduled one, because the three-hour threshold is measured when the doors open.
