Know the feeling too
SA, had no problem with management though, they were great, just totally fed up with three nights a week Tenerife, Rhodes, Heraklion etc. and weekends Palma, Malaga, Alicante etc. in a B737-200 and no prospects for change. Stayed away just over two years and then came back to flying. I took my sabbatical at forty two and was back by forty five, the older you are the harder it is to return, usually.
Have you considered working for the CAA? Plenty of BS still but at least you would be a part of it!
Farnborough takes about eighteen months to organise, have you considered working in operations support with the air show organisers?
Paid manager of a flying club/school, opportunity to fly for fun, not much money.
Become an expat. enjoy life a little!
