Are you Mikey O'Leary?
You do realise he will change the prepaid card you can use from time to time? And given more profit comes from 'other charges', if you keep beating the system then the system will change.
Fair play to you playing by all the rules and bending over backwards to avoid all the fees - but don't be surprised when you see the planes getting emptier, which will in turn see cuts to routes (which has already happened). And it isn't just spelling your name right, but things like getting a passport number wrong. I bet people do it all the time.
Ryanair needs to make that extra money, as well as people paying top dollar for tickets so you get the 50p jobs, and I am not sure how sustainable it will be. Remember too, he did very well by speculating about increases in fuel costs - and saved loads when other airlines suffered - but that's over now.
