As far as the new NJA FDP pay goes.. I'm in the CL-350. I'm a CPT.. but FO's make the exact same FDP pay as the CPT. Last 7 day tour I made over $1600 in FDP pay (that's on top of my normal salary). My FO made the same extra pay. I'm on track to do that again this week.
I think that the different fleets will vary in this extra FDP pay. But I figure it will add an additional $25K - $30K per year on top of the new salary. FWIW
