I fly with wizz quite often and they are cheap, but you always get stung on the little extras. Even the hand baggage deal costs, what you can take on as hand baggage free is not much more than a kids satchel, in fact my four year olds Elsa bag was technically too large, if you want to take a standard size cabin bag on board they charge. If you are likely to fly a few times in a year with them then pay for a years membership of the wizzclub, it paid for itself on the first booking for us. Good cut price airline though if you don't expect all the frills, steer clear of the car hire deals though, they are never what they seem.
We flew back into Luton last week and the pilot came in too fast and a few metres above the tarmac bottled it and pulled back up, bum twitch moment, most of the plane applauded when he got us down the second time, that was after a 30 minute fly over the home counties.
