Judging by the recent Norwegian Air Shuttle recruitment drive it seems 1,000 hours is the minimum for them.
In the good old days it was 700 hours for a CPL and a first job required 1,000 hours after slogging through hours building by instructing or the like.
In the early 2000s easyJet required 1,500 hours on turboprops or jets - so yes 1,500 'good' hours were required.
Things have changed so much and, as we all know, pilot training has improved to the point where it is now adjudged that super Cadets with 250 hours are just as safe as those pilots who ten years ago required ten times the experience to do the same job.
