It would make sense if they have. The average Break-Even for the type is in excess of 600 seats occupied.
BA loses money every time they fly the 380. It's over heavy,
Supply your referenced evidence to justify such a statement please !
Especially when NO ONE flies these with more than about 520 and the 388 is certified for 550 in a three class configuration.
I believe you are very wrong in such an assumption.
