I came from the corporate world over to NJA almost 11 years ago. Now, after being an IOE instructor and training people from both the corporate side and airline side, I can give you a few comparisons.
1. Corporate guys know the ropes about operating private jets better than airline guys. I'm not talking flying skills here. I'm talking attention to detail. Corporate guys are already up to speed (for the most part) on proper cleaning and servicing of aircraft on this side of the industry. Airline guys tend to not bother checking tables or wiping things down if there isn't any catering on board. Pax still leave fingerprints whether there's catering or not, but it's one of those detail things that airline guys mostly miss but folks from the corporate world understand.
2. Folks from the corporate world are already used to the personal interaction we have with pax that simply doesn't exist in the airline world. Not saying the airline guys aren't personable, just not up to speed on interacting with the pax the way we do in corporate (fractional) aviation. Once we level at altitude the corporate background guys are much better at taking the initiative to go back and check on the pax than the typical airline guy.
3. Corporate guys tend to have an easier time adjusting to the ever-changing circumstances of our type of flying. Coming from an extremely rigid type of schedule at the airlines tends to frustrate many of the airline guys here when our daily schedule keeps bouncing around. Changing destinations enroute is always an interesting exercise with a newhire who came from the airlines. But this is all old hat to a corporate guy.
4. Corporate guys tend to be a lot more proactive when dealing with typical problems we encounter. For example, if the pax catering doesn't show up, the corporate guy already knows 4 different ways to get food quickly for the pax, whereas the airline guys typically only think to call the company and let them sort it out.
Please folks, this isn't a slam against airline guys. The initial question was about corporate guys coming to the fractionals. Truth is, everything I said above is correct. The guys with the corporate background do INITIALLY have an easier time making the transition than the airline guys do.
I'm only talking about the initial transition in everything above. Once up to speed, the airline guys are just as good, and in some cases better than, the corporate guys.
