Apart from the quality of landings and other rubbish, I would say that these top guys moving from one major player to another player is no more significant than a "professional, qualified and experienced" person moving to another outfit requiring a "professional, qualified and experienced" person with appropriate background.
Basically we all have a career to run... I wouldn't read too much into it.
On top of that I agree with Daifly and his view on how relative things may be.
Still, I wish Vista Jet good luck. If they manage to stimulate the market, we will all be winners in the end.
(Plus I prefer their paint scheme to ours
