About 100 flights a day flew in Ukraine’s airspace in May, down 89% year over year, reports UkSATSE, the national air traffic control agency. Next Monday, after a 3-month suspension, international flights are to be re-started in and out of Ukraine. Last Friday, domestic flights started from Kyiv Boryspil to Odesa and Dnipro. But UkSATSE reports: “Experts estimate that a return to the volume of pre-crisis flights can last up to two years.”
