A remark to AirBus Driver's figures. I'm afraid your load factor figures are not correct.
Long Haul : Between 60 and 80 percent is correct, but ticket prices are very cheap due to big campaign. Yields are very low.
Meaning even if you fill an Md11 up to 95 percent and fly to Hong Kong and back you'll have a massive loss.
Short Haul : Correct load factors are between 52 and 58 percent.
On most routes there is a brake-even with about 25 percent load.
(Depending on route, day and aircraft)
So don't come with all these fact's from you're bottom of reality.
