On the button, and I've just done a paper saying much the same in 1500 words of elegant prose, statistics, factors, conclusions etc.
Short, pithy, accurate statements like your last para can do a lot of damage to us BS merchants.
By the way, care is needed with assumptions about LCC fares and their passengers; there's a large Irish outfit that gets quite high average yields; the magic is worked by add-on charges but mainly because a small number of seats are sold at very high prices indeed, especially where competition is not strong, and a larger number at a fairly high price. There was a time a year or two back when on some routes they had a higher average yield than BA. Recently its average fare (ie excl taxes etc) was 49 Euros.
Flybe, which tries to be an LCC while looking more upmarket, will hit you for £280 (inc add-on charges) to get from EXT to JER and back, if you want to go at fairly short notice. Low fares are very few on that route. But then no-one else flies it.
