If Ryanair are guilty, then so are lots of airlines. Easyjet, BA, bmi, FlyBe, Transavia, Wizz Air, SkyEurope, Air Berlin, flyGlobespan are but a few I have been tempted by shockingly low fares only to discover that my "£1" fare actually balloons to £40 or £50.
But still, I think in Europe we are a bit spoiled. When throughout the history of air travel could you fly from the UK to Poland for £40 return? Who honestly expects to only pay £1 for an air ticket anyway?! Does it really matter exactly how the money you pay is divided? Enjoy the low fare era while it lasts, instead of hunting for reasons to end it.
