Funbags ...Twaddle
We have been doing SYD/MEL for years...no one panics.
SYD/AKL/SYD when we ran the show...full bar...full meal and duty free...FLT usually less than 3 hours...full pax load on a jumbo
The only crew who panic on these sectors are ex domestic old boilers.
Funbags...I gather you are a Techie...how the hell do you know what goes on in the Cabin?...you never leave the flight deck except to get off the aircraft.
