"would they accept an app. from someone with 250hrs Turbine SIC part121 time(500 total), or some CFI with 500 hrs total(150-200 multi).........."
No. But if airliners were hiring at 500 hours, the CFI would have the better chance over someone in PFT.. My 2 cents.
I was looking at Gulfstream as well as some others (Comair) until someone told me about ATP and then someone else told me there was an ATP forum here (I think Alchemy, not sure).. and then the rest is history.. well, up until now.
Just so you know, Pay for Training (like, you pay 10000 and sit in the right seat of what would normally be a paying job) has a really really bad stigma in the industry, as does Gulfstream Academy and Gulfstream International Airlines...
Doug: I know it's hindsight, but that whole ATA looking back looks like someone shoulda' seen it coming. That owner sure looked like he was in some shady dealings..
Atleast we can all laugh at Discovery Air.. have those assets been liquided yet for some poor students?
