The story
Wizz Air Ukraine commenced domestic operations in Ukraine on 11 July 2008 and later added international flights. Domestic operations were later discontinued.
In October 2013, the airline opened its second base at Donetsk International Airport by deploying one aircraft and opening six new routes. However, the Donetsk base was closed by April 2014 due to the war in Donbas.
On 26 March 2015, it was announced that Wizz Air Ukraine would shut down by 20 April 2015 due to the Russo-Ukrainian war. Eight routes from Kyiv - half of them to Germany - were taken over by the parent company, Wizz Air, while the remaining ten routes from Kyiv and Lviv to destinations in Italy, Spain, Russia and Georgia currently operated by Wizz Air Ukraine ceased entirely. All of Wizz Air Ukraine's Airbus A320-200s were taken over by Wizz Air Hungary.
