Leaving Heathrow

Leaving Boston
Not covered on Delta Air Lines: Boston is outside the UK and EU, and Delta Air Lines 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 Delta Air Lines is not a UK or EU airline. It is per person, so four of you is £2,080.
How Delta Air Lines does on this route
Better or worse than the route itself?

On this route Delta Air Lines is 2.5 points better than the other airlines flying it.
Against its own network it is 4.1 points better than usual: Delta Air Lines lands on time 79.7% of the time across all 8,381 of its UK flights a year, against 83.8% here.
