Never had a flight where I thought I would never travel ryan air again .. but I hope I never experience sitting next to the horrible slob I endured on my return journey .. no fault of airline or crew. Though the seats are a fair bit narrow, the lad sitting next to me had part of my seat, he was a big lad to be fair so sat with knees spread wide with his bag in-between them, so I had to sit awkward, then the entire journey had snot running from his nose, he had no tissues .. 😳.. I'm glad I wasn't eating .. anyway, that's the negative done 😆 . My journey on the way out was all positive .. only went downhill on return journey lol.
