The restoration of the former air traffic in Ukraine may take one and a half to two years, Minister of Infrastructure Vladyslav Krykliy said. "Our forecasts are the following: if we start reactivating a little in June, then by the end of the year we'll reach about half of the passenger flow that was earlier. But in general, aviation is inertial. Therefore, we will return roughly to the previous passenger traffic in about a year or two," he said during an online meeting of the European Business Association on Tuesday.
