These clowns want to "burn down the house"...and dont much care for who resides in it....very UNPROFESSIONAL for sure
Certainly true of a couple of PIT crews I spoke with a several months ago. They were going to trash the place and make a statement on the way down. They must be disappointed that the company has survived this long.
Still, there is a real cycle of "fuel savings" programs. Fuel loads are cut back, fuel is saved until a few expensive diverts occur then more fuel is put on the flight plan and the cycle starts anew.
