Wizz Air are offering 20% off all flights and all destinations.
You need to travel before May 31, so not many dates available.
But a great deal if someone out there is looking for a last minute flight.
The fine print:
*20% discount applies to fares including taxes and non-optional charges but excluding administration fee. This promotion applies on 12 April from 00.00 to 23.59 CET. Travel period is limited, all travel must be completed by 31 May 2018. The price applies only to bookings made on wizzair.com or on the WIZZ mobile app.
