(it's not the pacific but similar distance)
CX HKG LHR. Same day. 744 vs 773. Same route (B330) and time ( I asked the planners for a comparison). Almost identical pax loads. In other words apples v apples
773 trip fuel 100.6 Ton
744 trip fuel 133.8 Ton
If you did a 380 run it would be around 150-160 ton.
QAN_SHAREHOLDER if you run the numbers on pilot costs, you will find Qantas pilots sit right in the middle (I have done a CX, SQ, BA, VA, QF, EY, EK, QR, SAA comparison based on both current and a floating average). Whilst the exchange rates have moved, it does not affect the rankings as much as you are suggesting and CX are still the highest paid pilots in the region. In fact their contract has a built in fixed exchange rate of just over 6.1 HKD/AUD.
As for CEO costs, AJ is miles in front of pretty much every other major competitor we face.
