So what's all this?
I have flown Ryanair precisely twice, both times when someone else was paying.... The only way to do it in comfort is to pay extra and sit in the very front, next to the door, where legroom is plentiful. Otherwise don't, unless you want to become a cripple. (Easyjet is just as bad for seat comfort and seat pitch. Never again.)
When I first looked at the thread title I thought it said SIN-LIS-SIN. Say it ain't so, I said!
But even STN is horrible; the car parks are horrible; and for anyone living southwest of London it is horrible.
Never again. Really. Never!
