Note this is from a US paper. For young US pilots - this makes sense.
Start off in commuter to get PIC time, not as career, when you have enough hours then...
Join CX to get heavy time, not as career, when you have enough hours then...
Join UPS/ Fedex until retirement
So CX is a means to an end.
Given number of US crew leaving CX for UPS/FDX after just a short time in CX, any wonder that they aren't that concerned by the pension/ medical, just the take home pay?
