REUTERS Ukrainian Infrastructure Minister Vladyslav Kryklii says regular air transportation services may be resumed in August or September 2020. However, he suggests, it will take about two years to reach the pre-crisis level of operations. Kryklii says this depends not only on Ukraine, as it had been mostly operating international flights in the pre-coronavirus period. The minister has told 24 TV Channel it is rather difficult to predict when and how quarantine restrictions would be lifted in other countries. "I can&#39;t imagine that by the end of summer Europe will fully reopen its air gates and engage in tourism as it was before the coronavirus outbreak," Kryklii said.
