The Financial Times reported the information.Low-cost giants Wizz Air, Ryanair, and easyJet have outlined ambitious plans to establish or expand operations in Ukraine once the country's airspace reopens to commercial traffic. Wizz Air, which was the largest international carrier serving Ukraine before the 2022 Russian invasion, intends to station 15 aircraft in the country within two years of a peace deal, eventually expanding to 50 planes over seven years."We have planned for this, as soon as the airspace opens we are going to be very quick to re-establish ourselves," said Wizz Air CEO József Váradi. "Re-opening would be a significant opportunity for us."Váradi predicted an unusual travel trend: what he called "catastrophe tourism," where people visit sites affected by war or disaster. "When the Berlin Wall came down, millions of people went there to see it," he noted.Ryanair is positioning itself for an even faster return. CEO Eddie Wilson said the airline could have flights on sale within two weeks of airspace reopening and aims to transport 4 million passengers annually, nearly triple its pre-war numbers. Before Ukrainian airports closed, Ryanair carried approximately 1.5 million passengers per year to Kyiv, Lviv, and Odesa."You can fly from Dublin, Shannon, Cork, across the UK or Europe, you could have three, four, five flights a week," Wilson explained. "There wouldn't be any difficulty whatsoever filling 4mn passengers over there."EasyJet, which never previously operated Ukrainian routes, is also exploring entry into the market. CEO Kenton Jarvis described Ukraine as potentially "Europe's largest construction project" and noted that people "will want to come home when home is safe.""It's a missing part of Europe right now," Jarvis said, though easyJet does not plan to base aircraft in Ukraine initially, unlike its competitors.Before the full-scale invasion, Ukraine's aviation market was substantial. Nearly 15 million passengers flew to the country in 2019, dropping to 10.8 million in 2021. Wizz Air handled over 5,000 flights to Ukraine that year, making it the third-largest carrier after Russia's Aeroflot and Ukrainian charter airline Windrose.Currently, the EU's Aviation Safety Authority advises against flying over Ukrainian airspace or landing in the country, citing safety risks from ongoing military activities. According to aviation consultancy Cirium, only one airline—Russian carrier Smartavia—has registered flights into Ukraine over the past two years.The tragedy of Malaysia Airlines flight MH17, shot down over eastern Ukraine in 2014, remains a stark reminder of the dangers of operating in conflict zones.
