I think ryanair would just reduce the seat size and spacing between the seats.I often wondered whether there should be an overall passenger+luggage allowance. Skinnies can take a full suitcase, fatties just a toothbrush. That might help address the country's obesity crisis.
if you can’t sit down you can’t fly. The plane is still leaving so you dont get a refund.
that’s the O’Leary method
