Gee, you make it sound so great to be a Jetstar pilot.
Every single one of those "efficiencies" is going to either work the pilots into the ground or screw them for promotion.
All this and being paid less than the going rate to boot!
Try getting shorter nightstops and more efficient patterns out of a flight that goes to a destination once a day, if that.
PS, AIPA has nothing to do with not allowing a 767 base in Melbourne, it's purely a company decision.
