Stupid question here, because I haven't flown with Ryanair in like almost 10 years, but I've recently flown with WizzAir and after checking-in online (the night before) it generated a .pdf boarding pass which I saved on my phone. I was then able to get onto the plane by presenting the QR code from said .pdf, i.e. while I was at the gate, no need for internet access. Does Ryanair do things differently?
