Piedmont: ~81-84 hours for lineholders (used to be closer to 88-89 hours prior to Part 117.) Contract says lines have to be built between 80-90 hours. Lineholders generally don't do a lot of DHing. 75 hour min guarantee. Trip rig is 4 hours/day (averaged over the trip...ie one day could be 2.5 hrs and another 7, as long as it averages above 4 for the trip. DH-only days pay a minimum of 4 hours.) Mix of 1/2/3/4 day trips, but lines average ~12 days off per month and are rarely commutable. No idea what the new PHL base will look like.
I'd say I have averaged right around 90-93 hours of credit after over-block and soft pay over the last 4 years, and I don't pick up open time.
