What's your opinion then of Easyjet and Ryanair?
I am quite a fan of easyJet - they do what they do very well, and they do it very professionally indeed. I have personally spoken to Carolyn McCall and think she has a lot to do with this success.
The one thing I think they should pack in doing, now they have abandoned the rock-bottom fares competition in favour of being Premier Inn rather than Travelodge[1] (if you see what I mean), is charging for the first checked bag, as this, and this alone, is the cause of the excessive cabin baggage problem they have.
I dislike Ryanair because they seem to be the embodiment of cheap rubbish, despite on the face of it operating a similar model to easyJet. Wizz Air are even worse.
Maybe it would be better then if they didn't provide an English version at all?
If they are going to provide an English version, it should be correct, and if they can't be bothered to ensure it is correct it indeed should not be provided; they should run it past a native speaker for proofreading. Whenever I have worked on projects involving translations, we have always done that, it has never been deemed acceptable just to whack it into Google Translate or guess.
The problem is greater than just translations, though; companies these days seem to see proof-reading as something that is valid to cut.
[1] I quite like Premier Inn and Accor/Ibis, and like Motel One even more - they are relatively budget hotel chains, but concentrate on doing a good job of what they do without imposing artificial requirements to make things worse. I near enough refuse to stay in a Travelodge now, because I have got thoroughly sick of dirty rooms and broken fixtures - which is a similar level of can't-be-bothered sloppiness.
