The ability to live where I want is a fundamental enabler of my career choice.
Take that away and I'm out. The airlines can't afford to pay me enough to move to DTW, JFK, PHL, etc. every few years. In addition to QOL of life and family stability issues it takes away another key enabler of airline pilot careers: the spouse's highly-compensated career.
I'm guessing I'm not the only one either.
