FGD, this is the problem... you have no idea about how pilots are paid.
The only time QF pilots are paid for doing nothing is if they are not utilised on a reserve line.
We are paid the greater of 5.5 hours credited hours a day or flight hours flown. In the A380 example I quoted you the crew was on a 9 day trip. They were paid 50.3 hours credit, were on duty for 49 hours and logged 42.6 hours flying, about 2/3 of it at night. They got 6.4 hours overtime. Add to that ODTA and super.
A roster for an A380 pilot is currently 160 Credited hours but they can be rostered to 175 credited hours. You only get paid for the credited hours you do.
Therefore the PAY that each pilot receives for each flight is very easily calculated and accounted for. Therefore the cost to a passenger is also very easily calculated.
Now if you wish to talk about COSTS, that is another matter. As I said before, pilot COSTS are a COST of doing business and would not vary substantially from airline to airline. A J* pilot has to be checked and trained, accommodated and fed whilst on duty, flights have to be crewed etc etc same as a VOZ, Cathay QF etc etc.
None of those COSTS bear any relation to what the pilots are being paid, nor do pilots have any significant input into them.
If you wish to have your aircraft flown however, a business must pay those costs.
The fact remains however, that of the $2000 most people pay to go to London and back, $40 of that ends up in the pockets of the flight crew. It works out at less than a dollar an hour/per passenger for a 15000 hour Captain, a 10000 hour F/O with an A380 command endorsement and two S/O's who are guaranteed to be experienced.
The figures will vary of course over different fleets and patterns with differing amounts of seats on the aircraft/hours flown/crew compliment etc but if you are telling me that we are expensive and need to take a pay cut to save the airline.... sorry I beg to differ.
The other flaw in your argument of course is that, despite all its troubles, Qantas is still making a profit. A lot of that profit comes from LH pilots flying domestically on the 767, A330 and 747.
