Hi. I also quit. Used to hold various managerial roles in small/medium airlines. Some failed so I ended up in the dole-queue. At least I had made some money so that I could afford to look around. In the meantime one of my pensions started to pay.
Like the original poster said, it used t be fun. Nice crews, good fun nightstops, great aircraft. But recently I had a Chief Pilot (also CRM instructor!!!) who rings up FOs to find out which old LHS bods are not following Part 8 to the letter, etc.
So I got out and took a groundbased job, whilst saying NO to job offers in the pits of Europe, Middle East and Far East.
Now I can sleep in my own bed every night, have weekends off, see my family and grandkids. I earn less, but I am HAPPY.......
