Is it in the rules that you need to print the BP first? Yes. That doesn't make it any less absurd. Totally agree with ralfkrippner.

On all the times I need to fly cheaply intraEurope, it's policies like these that make me never consider Ryanair. They lose probably 500-1000 euros/yr because I'm not confident enough in my ability to avoid accidentally incurring some asinine charge.
