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
