PFT started around the early 1990's. Most had it. You paid $350 for a Flight Safety evaluation, then it was around $9500 plus living expenses for training. My carrier at the time started using PFT pilots in 1993. When Northeast Express shut down, I missed the last non PFT class at CO Express and was offered a slot in the first PFT class. IIRC, some of the commuters that were not PFT were AE, Piedmont and Horizon. Since there was little hiring, jobs were though to get. ValuJet was PFT too.
