UKs Ryan Air was even proposing ideas of having people stand during flights (yep, its really that ridicolous) and letting people pay to use the lavatories...
Not that they would get through with that but still, they are searching for every inch to make more money.
Those crackpot schemes are just designed to get their brand in the Daily Mail and in turn, for people to talk about Ryanair. (their headquarters are in Ireland, not the UK)
Is it Ryan air that gets all its air hostesses to paint their faces with orangeish makeup? I have a recollection of a collection of air hostesses in skin-colour-inappropriate makeup from a trip a few years back.
The CEO said it in jest because even bad headlines is good advertisement. I don't think anyone of his engineers would have seriously considered implementing it. And that's not even counting the insurance underwriters and CAA who would have shut it down.
Honestly, after sitting at my desk all day/week... I actually wouldn't mind standing on my usual 50 minute Southwest flight. Not that the FAA would ever allow it.
