replacing them with a totally unsuitable and decrepit aircraft like the 747 classic.
How much did that exercise cost QF I wonder?
That's one calculation you've got wrong sorry Kremin! The Classic made a motza on that run, in spite of its problems.
'Twas very rare to have less than 450 PoB (full was 467) on the aircraft. Both classes had inseat IFE (albeit fairly average) and full inflight service including meals and booze (important for the east coast FIFO!); yields were high.
