What you're owed

Leaving Heathrow

£520each under UK law

Leaving Atlanta

£520each under UK law

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

Heathrow to Atlanta is 6,761 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 Delta Air Lines does on this route

Better or worse than the route itself?

Everyone flying Heathrow to Atlanta 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.

Delta Air Lines flies 60% of this route, so the right-hand column is mostly its own flights being averaged back at it. The comparison that means something here is against the rest of its network.

Against its own network it is 1.5 points better than usual: Delta Air Lines lands on time 79.3% of the time across all 8,476 of its UK flights a year, against 80.8% here.

In money terms: about 13 flights a year on this route land 3 hours or more late, which is about 1 flight in 170. Everyone on board one of those is owed £520 each, so a full aircraft is a five-figure bill for Delta Air Lines.
