Don't get me wrong, I don't have any issues with their policies, and if they want to overbook, why not? Most of the other low-cos do! But to actually advertise that you're one of the only European carriers that don't overbook, when this is a blatant lie, is pretty poor!
I would love to know what their no-show rate is.
Very high, the average is certainly in excess of 5%. Even when the flight is overbooked, they often manage to accept 5 or 6 standbys.
But, there will be the rare occasion when the majority of passengers turn up, and inevitably, some are denied carriage. To then lie about the reason, so that they can claim to be something that they aren't, is poor!
