Wizzair is offering an "All You Can Fly" program.
For 599 Euros, and an additional 10 Euros per flight, you can take as many flights as you want on the Wizzair network for one calendar year. (Domestic flights in Italy excluded). You can only book between 3 days and 3 hours before departure and it is only for the basic fare. You can add on extras.
Anyone interested?
