On the 19th of May, Wizzair (link) will celebrate its 10th birthday. For this anniversary Wizzair runs a great “buy 1, get 1 more for free” promotion. From midnight you will be able to book 2 flight tickets for the price of 1 on the same flight operated by Wizz Air Hungary. One out of every two tickets purchased will be free. One reservation can include max. 5 free tickets. Valid only for bookings made on the 19th of May! If you are still planning your summer holiday, I strongly recommend you to wait until mindnight! There are a lot of sunshine destinations in Europe where Wizzair flies, for example: Barcelona, Malta, Corfu, Mallorca, Malaga or Dubai. However, you should plan ahead today and have to be ready for booking by mindnight because the cheapest tickets can be sold very soon.
