What an utter load of rubbish! I think you'll find both EZY and RYR are most likely to whether the storm over your traditional carriers. Punters are feeling the pinch in Europe, as well as the States. They are going to be far more attracted by the low fares of LCC's, with no fuel surcharges etc. Yes they have to pay for a few extra things, but if they are wise and cautious then they'll get a cheaper fare generally than offered by a legacy carrier.
All airlines are reassessing their strategies, but you cannot say that RYR will suffer most, because they have proven that they quite clearly wont. They might only break even next year, however watch this space, others will lose money.
