Almost all ... well thats as good as saying 95% lol
Anyway , lets put semantics aside.
I dont think any of the guys in Air China , living in Oz on tax free $US22000 a month have any regrets . How many there now , 10 or so?
And the one guy who did come back to KA lost his CAAC medical , but openly says he would still be there if his licence wasn't taken away.
Oh , how about the new A320 skipper who left last week to go to Virgin Atlantic . Bet he really regrets it.
The only poor b#%#tards who regret it were Sacked so had no choice. The guy in Fiji airways comes to mind .
