As for the "low cost model " and my post about management as a group, cutting too deep on a worldwide basis. Watch what happens when aircraft start leaving big smoking holes on a regular basis. Prices will then rise...and the public will be glad they did.
Easyjet and Ryanair have now been operating for 10 years and so far this has not happened. And this despite them operating short haul routes where there are for more takeoffs and landings per mile travelled and hence more likelihood of problems.
Perhaps they have just been lucky or perhaps, unlike AdamAir, they realise which costs you cannot afford to cut beyond a certain point.
