I believe Gengis is certainly right with, ""far more interesting to work for small companies in the design field".
The interesting times for a designer in the large companies you mention are long over. But especially if you wish to go into the commercial pilot direction, a design job in one of the large company will gain you nothing. As far as earnings is concerned, I would not expect too much. Maybe BurgerKing will give you a better balance between earnings and free time (to work on restoring A/C etc)
There's a negative old git for you.
