SXB, I do hate this flippant often given answer, "you get what you pay for". I don't believe that's quite true. It may well apply to those who have been able to book early and benefit from the gimmick "throw-away" fares, but it does not apply to late bookers. Book late with an so-called LCC and you most certainly do NOT get what you pay for!
I'm not convinced that charging for every service used individually is that cost effective. Any perceived gain will to a large extent be cancelled out by the additional costs in administering and monitoring it all. All the hassle may well in time drive the revenue generating pax (i.e. late bookers) away from the LCCs and that will trigger their eventual demise.
I can live with pay-as-you-go in-flight service on short haul. For the rest, I'd like to see the industry retaining some common sense and taking stress away from air travel rather than adding to it.
I avoid the likes of Ryanair like the plague.
