I flew AMF ended up in the 99. I thought some 121 time would be needed so I went to Mesa (worst 4 years of my life). Now I'm at America West. A friend of mine stayed at AMF and flew the Metro and never went to the regionals. He's 30 numbers SENIOR to me at America West.
Trust me, freightdogs are not looked down upon. If you've got the turbine PIC then you're fine. If I had it to do over again... I would have stayed at AMF and did what my friend did.
