What you're owed

Leaving Istanbul
£350each under UK law
Istanbul is outside the UK and EU, so coming back this only applies if a UK or EU airline operated the flight.
Heathrow to Istanbul is 2,487 km, which fixes the figure: £350 each leaving Heathrow, and the same £350 each coming back if a UK or EU airline operated the flight. It is per person, so four of you is £1,400.
How Turkish Airlines does on this route
Better or worse than the route itself?
Everyone flying Heathrow to Istanbul 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.
Turkish Airlines flies 69% 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 3.4 points better than usual: Turkish Airlines lands on time 73.3% of the time across all 12,764 of its UK flights a year, against 76.7% here.
In money terms: about 9 flights a year on this route land 3 hours or more late, which is about 1 flight in 500. Everyone on board one of those is owed £350 each.
