Gonna have to play devil's advocate here. First off, I DO NOT agree with PFT - although the argument could be made that the ATP'S and such are not that much different.
I have a friend that was an FO at Eagle for 5 years - going nowhere fast. He left Eagle for a street CA position at Gulfstream about a 1-1/2 years ago to get PIC turbine time. He got his 1000 + turbine PIC and is now an FO at Southwest. Is he at fault for flying for GStream? I hardly think so. Did it get him his dream job? Yup, Southwest is not a bad gig. Did Southwest care he flew at GStream? Obviously not.
While I was formerly buzzing around in the 717, I had a couple of different FO's that were former CA's at GStream. Good pilots, nice guys, not a problem in the world with them. Obviously my former employer had no issues with where they flew previously.
Does GStream have good schedules? Couldn't tell you - but I doubt they can be any worse than other regionals out there. Do they have good pay? Probably not - but what regional does? Do they have any accidents resulting from inferior mx? None that I'm aware of. Do they have crappy management? Probably, but I doubt it's any worse than say Mesa, that Hulas guys companies, or many other regionals out there. Do their CA's get hired by "good" companies? I can vouch they get hired at AirTran, my buddies at Southwest - and he says their CA's are at Spirit, Continental, UPS, Frontier, NetJets, FlexJet, Citation Shares and a slew of other operations.
Again, I am completely against PFT. BUT, I think the GStream fear factor card is waaaay overplayed these days by alot of folks out there. Does GStream hire "the best of the best" - doubt it, but what regional these days does? Personally, I think if someone flew for GStream it is clearly proven by whom is employing them after GStream that flying for them is not a factor.
Just an opinion, but I think one that reflects the present in the airline industry - not the past.
