Spread of more F and C over 2 A380s and 3 B77Ws means Y fares can be lower than MAN with 1 A380 and 1 B77W.
Very true. However you also cannot avoid the fact of the 10s of other airlines flying East in direct competition...
There is also the "we charge what we can" aspect .....
prices aren't set by working out the cost and then adding a percentage .. the market is also looked at and once your costs are covered you price according to what you think the market will cough up.
It's called supply and demand. PED is king!
