They are generally punctual, and the staff is usually young, kind and professional. But Wizz Air is a tipical ULCC. The base fares can be extremelly cheap (from 10 EUR), but you have to pay extra for everything, except air maybe. Recently they changed their policy, so it became worse. For example you don't get a seat automatically next to your partner, you have to pay for it and only a very small bag (40x30x20cm) can be brought to the cabin for free. So if you can deal with these circumstances, you can fly with them for coins.
