Just completed a round trip with Ryanair, Alicante/Stansted. Having read the cabin luggage rules I made sure my cabin luggage complied with the dimensions and weight restrictions. I was therefore somewhat surprised that many passengers, who ignored these restrictions and had, obviously, oversize luggage went through boarding, at both airports, with no trouble at all. The upshot of this was that the overhead stowage compartments were full to the brim and the last boarding passengers were compelled to stow their luggage under the seats, as best they could. So, after all the threats of oversize luggage having a payment penalty etc. why do Ryanair staff apparently choose to ignore it? Other than that the flights were excellent value for the money.
