In an ironic twist of fate, just about all of us expat airline pilots dream of the same thing ... an acceptably well paid, family friendly, nice little 9-to-5 GA job in our home country, that we could take an early retirement to. They are as rare as unicorn
and I would suggest they are even harder to find than an airline job, because they're always recruited by word of mouth, they're never advertised.
The answer for you my friend lies in helicopters. Seriously. There's a lot less of the silly ageism and pseudo elite airline nonsense. I know a couple of career changing guys who got into it much later in life and pretty quickly started making good money, one with the police and one in the oil & gas business.
