Flying for a living?
I guess you still me flying for living?
I would love to do all on the list, but as a have to feed my family a lot of those "jobs" is not really a choice - I did both parachuters and glider towing, and I loved it :-) guess I could also do scenic flights the rest of my life, but should have thought about that before I got kids to pay for ;-)
So I do not see its about the choice of airline or not - its a choice about what can you make a living on. I would fly anything that has 2 engines and 2 wings, and pays me ;-)
