There's something like 70 London to New York flights a day so in theory yes from a passenger numbers PoV it could support the A380 once there's terminal infrastructure.

But one of the reasons BA run so many flights (10?) a day is so that customers have choice and flexibility - it's not unknown for people to book business or first class seats on multiple flights in the same day so they can fly earlier if their schedule allows

Sure, there is convenience to having multiple flights a day. However, over say a half-dozen, diminishing returns kick in.

Well BA run 12 flights a day between London and NYC (9 from Heathrow, 1 each from City and Gatwick) and it seems to work for them.

They're catering to the people traveling business class who want flexibility and it seems to work for them - they run something like 86 biz class seats and only 140ish economy on some flights
