I don't see what the problem is with ryanair. They are cutting back on luxuries but they are also cutting ticket prices. I'd rather pay for what luxuries I do want and not ones I don't, than pay for a package that includes things I don't want or use.
Yes I think they should charge to use the bog. If people are too disorganised to go before they get on the plane then that's their own problem - ryanair are having to pay to have the bog on the plane in the first place, so why should I, as someone who remembers to go before I get on, have to pay my share of that amount for those who don't?
One way in which I think they could also save money is to let people lug their own suitcases into the plane. All they would need to do is to provide the same platforms/escalators/cherry pickers/whatever apparatus the baggage handlers use to put people's bags on the plane, but let people do it themselves. All you would need is one supervisor to make sure people were doing it right and not nicking anybody else's bag, you would only need about 2 baggage handlers per plane instead of about 10 or 20 that they probably have currently.
You get it off again yourself at the other end as well.
This would obviously also double up as a massive boon to people with bikes, as you could make sure it isn't being knocked about as you are doing it yourself.
What with the growing popularity in cycle touring they could advertise this as a feature of ryanair because i'm sure the jet-setting cyclist's biggest worry is baggage handlers damaging their bike by being careless.
Also instead of having a bus that takes passengers from the car park to the terminal, they could provide bikes that can tow those luggage trolleys, and then make a charge for using that bus for anybody who doesn't want to/can't cycle.
