Jackets have been an issue in QF because of the current policy. The policy dictates that the Capt makes the decision whether or not they are worn, meaning that most crews will pack a bulky piece of clothing that may or may not be worn depending on the whim of the PIC.
As has been said a few times now regarding various other elements or procedures when working for qantas...."They don't do that **** in short haul."
Departure status? Work it out yourself champ.
