Which rules cover LHR–BOS
London → Boston
Whatever the airline, this direction is covered by UK261 (the flight departs from the UK (Article 3(1)(a)), whatever the airline) and US DOT (the flight arrives in the United States (14 CFR 260.2, "covered flight")).
Boston → London
Whatever the airline, this direction is covered by US DOT (the flight departs from the United States (14 CFR 260.2, "covered flight")). On an EU airline or a UK airline it is also under UK261.
What you could be owed by hours late
Arrival delay at BOS (or LHR on the return), for a delay caused by the airline, per passenger, where each rule applies:
| Hours late | UK261 | US DOT |
|---|---|---|
| 2 hours | £0 | Nothing |
| 3 h 30 min | £260 | Nothing |
| 4 h 30 min | £520 | Nothing |
| 6 h 30 min | £520 | Refund if you decline |
| 9 h 30 min | £520 | Refund if you decline |
At 5,240 km this is a long-haul flight, so the first hour of compensation is reduced: arriving 3 to 4 hours late pays £260, and the full £520 starts at 4 hours. The US column is the refund right only: an international itinerary needs 6+ hours.
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 Boston Logan International Airport (42.36306, -71.00639) that is 5,240 km. The nearest band boundary is 3,500 km, 1,740 km below this route, so the band is not in doubt. Among the 18 routes on this site in the over 3,500 km band, it is number 15 by length.
Other routes from London Heathrow Airport (EGLL) on this site: New York (5,540 km), Los Angeles (8,760 km), Toronto (5,707 km), Dubai (5,498 km), Dublin (449 km), Paris (347 km), Frankfurt (654 km), Amsterdam (370 km), Athens (2,427 km), Helsinki (1,848 km), Edinburgh (534 km), Glasgow (555 km).
Other routes from Boston Logan International Airport (KBOS) on this site: Dublin (4,803 km), Miami (2,028 km).
If LHR–BOS 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.
Help at the airport while you wait
On a flight of this length, meals and refreshments are owed once the departure is 4 hours late under UK261, and a hotel with transport if you have to stay overnight — whatever caused the delay. US law sets no meal or hotel duty; the large US airlines' published commitments do, and they are on the airline pages. Keep receipts for anything you buy: it is claimed back separately from any compensation.
Claiming on this route
