Out of curiosity I've heard a lot of UAL aircraft in DEN talking to ramp about APU use when coming into the ramp. It seems ramp/ops dictates whether or not the APU should be used. Has that decision been taken out of your hands? I heard a guy being a bit unprofessional the other day on the radio about not being plugged in but also wouldn't fire up the APU? Was that him being meek or making a point perhaps?

Thought that particular case was odd, as a UAX guy we run our APU as needed without external folks telling us how to keep our pax comfy.
