Then take into account jet bridge cost, ATC services, fuel, and all the other operational expenses and the cost stacks up very quickly.

The big guys are able to offset these costs by using big planes and spreading it out. AA’s 777-300ER as an example carries 304 passengers. 60 of those seats are premium lay flat first and business class. Then there’s the freight in the belly. (321 isn’t carrying any meaningful payload there).

All that payload and you can squeeze out a profit, hopefully. How JetBlue intends to make it work in LHR with an A321 is beyond me. Only time will tell I suppose.
