1,500hrs is not much time at all. I think that putting ATP (Airline Transport Pilot) requirements to fly an AIRLINER only makes sense. I know I learned ALOT between 250-1,500hrs, I didn't just spend my time VFR in a 172 though, instructed alittle, flew some traffic watch, then SIC 135 cargo and by just over 1,200hrs PIC 135 cargo. So by 1,500hrs I'd seen a fair amount. Never the less I still had more than my fair share of potential fatal situations well beyond 1,500hrs, more than I care to admit due to faults of my own, but I survived and learned from it. That's what experience is. So suck it up, for a couple years and earn your experience.
