What keeps Ryanair in business is being nimble, lean and very fit. This means it is able to adapt to and exploit any changes in its sphere of operations. If you don't confirm, you are out. This also gives the downside resulting in employees and contractors never being able to plan for what most people consider to be a future. Effectively, RYR is the corporate equivalent of a gypsy. Personally I don't do business with people who only have mobile telephone numbers, have "fat weddings" and crap in hedges purely because not only I do I not trust them, there's little I can do if something goes wrong. But it appears that the travelling public don't care. As long as it's cheap, they'll travel. Part of that cheapness comes from the way subcontractors are managed, ie. pilots. They too are paying the price and when Europe's tax officials start growing a few pairs, some also be paying some hefty back tax bills as well.
Best of luck.
