What you're owed

Leaving Heathrow

£520each under UK law

Leaving Boston

£520each under UK law

Boston is outside the UK and EU, so coming back this only applies if a UK or EU airline operated the flight.

Heathrow to Boston is 5,240 km, which fixes the figure: £520 each leaving Heathrow, and the same £520 each coming back if a UK or EU airline operated the flight. It is per person, so four of you is £2,080.

How American Airlines does on this route

Better or worse than the route itself?

Everyone flying Heathrow to Boston hits the same airspace and the same two airports, so the honest question is not whether the route is busy, it is whether this airline handles it better or worse than the others on it.

On this route American Airlines is 3 points better than the other airlines flying it, and its average delay is 3.2 minutes longer.

Against its own network it is 11.3 points better than usual: American Airlines lands on time 74.1% of the time across all 15,514 of its UK flights a year, against 85.4% here.

In money terms: about 13 flights a year on this route land 3 hours or more late, which is about 1 flight in 55. Everyone on board one of those is owed £520 each, so a full aircraft is a five-figure bill for American Airlines.
