I've flown for 5 airlines: 4 Part-121 US pax carriers (Two commuters. One LCC. And one Legacy). FedEx is my fifth (and hopefully final) airline.

ALL four of the previous airlines did the standard "start cleaning up at 1000 AGL type"-takeoff (NADP1). Of course, if there was a specific obstacle departure, airspace speed restriction, noise abatement requirement, etc, then yes, we did what was required.

FedEx is the first airline I've ever heard of that climbs to 3000' feet at EVERY single airline before nosing over and accelerating. The is the first change I've seen around here that is actually in line with what the rest of the airlines do.
