MAB...mate,
you shall know the industry better, either it is a small department and everyone is covering at least two bases, plus flying; and you can anticipate delays or no responses.
From Vista , it is like Netjets, a bunch of secretaries and an automated email response.
Whoever joined Vista, it is their own profile that was chosen, would it be because they knew someone from inside or whatever, it does not matter, if Vista publicize a job offer for TR captain, it is for a good reason, and if you want more info , you buy yourself a ticket to Malta, or take your phone, or whatever.
ho wait may be they put this od up because they were actually in need of FA ?
Did you get a positive info on your question ? nope, some people got their TR included with the purchase of the plane, the others get bonded for it...May be these guys applied for the GLEX ? who knows ? At the end of the day, PFO or not, I hope that you land your wonderful dream job at Vista in a very short period of time ( TR or not).
