Not a fan of budget airlines! Mainly because at the end of the day they are little,if any cheaper, than a schedule airline and to fly with them you have to put up with no end of messing about and inconvenience. Not to mention the poor quality and overpriced snacks. Trouble is these days, to fly to many European holiday destinations, they are the only option.
Having said all of that, within the species, they are as good as it seems to get in our limited experience.
