In November 2017, Wizz Air announced its planned launch of a British division called Wizz Air UK, based at London Luton mainly to take advantage of landing slots acquired when Monarch Airlines entered administration that year. The airline applied successfully to the CAA for an AOC and a Type A Operating Licence. The airline launched operations in March 2018 using British registered aircraft. Wizz Air UK was to start taking over UK-bound flights previously operated by Wizz Air, and plans called for the airline to employ up to 100 staff by the end of 2018.
In November 2018, Wizz Air announced plans to reactivate its Wizz Air Ukraine subsidiary, approximately three years after its closure. The airline would seek to complete certification in 2019 following the acquisition of twenty A320/321 neo jets. Bases were to be developed in Kyiv and cities across the country, with a planned passenger throughput of 6 million per annum by 2025.
