yes 3 crew on a 737 while the fourth is on a "break" one cart is half stocked too reduce the weight and they expect that the fourth crew member can sit down the back and do nothing. They spend the entire "break" getting service items for the rest of the crew doing the service. On a full SYD - MEL or SYD - BNE it's a complete joke and makes us look even more incompetent that we did with all four of us out there.
In real terms they will soon apply for CASA to operate at least the 737 - 700 with only 3 crew. Its only a matter of time..
