What you're owed
Leaving Heathrow
£520each under UK law
Leaving Boston
Not covered on American Airlines: Boston is outside the UK and EU, and American Airlines is not a UK or EU airline.
Heathrow to Boston is 5,240 km, which fixes the figure: £520 each leaving Heathrow, but nothing coming back, because American Airlines is not a UK or EU airline. 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 2.8 points better than the other airlines flying it, and its average delay is 3 minutes longer.
Against its own network it is 9.9 points better than usual: American Airlines lands on time 74.2% of the time across all 15,379 of its UK flights a year, against 84.1% 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 at least £260 each, so a full aircraft is a five-figure bill for American Airlines.
Other airlines on this route
Same two airports, same 5,240 km, same £520 each.
