I notice that Ryanair seems to be for quick flights, at least I assume, as you can’t really do anything on the actual plane (or the plane I was on) besides entertain yourself, ie. read, logical puzzles. There is no WI-FI, there doesn’t seem to be any outlet to charge your phone. The crew is very nice though and welcome you aboard. And they got us from A to B safely, so I’m very grateful for that! I also enjoy that Ryanair has converted its boarding passes to be online, it reduces waste overall. It’s not my favourite plane line but they got me safely to my destination and I would take that any day over WI-FI and a charging outlet. And the crew is nice so, I appreciate that.
