Ryan Air just introduced the super-annoying requirements of needing the app to download your boarding pass (which of course they could just provide from the website).
I think they do it to be able to send you notifications and sell you more flights, but I don't understand why they need to be so anti-user. I try to NOT fly Ryan Air unless there is no other airline available. I'd rather pay twice as much than support their poor and sometimes borderline-criminal business practices.
