Back of the envelope figures....
A 733 burning 2 tons/hour, flying for 16hrs a day costs an extra $288K to keep flying per month when fuel is $125/barrel versus $75/barrel.
Lets say an average ticket price is $75, WW need to sell an extra 3840 tickets a month to make up this difference.
A big catchment area with money makes a difference, especially when the same economics affect FlyBe, Thomson, Thomas Cook etc etc
