Turkish aviation authorities could impose retaliatory measures against Dniproavia (Dnipro) on the Ivano-Frankivsk-Istanbul route without permitting the company to fly on the direction after Turkish Airlines failed to get permit from Ivano-Frankivsk airport for flights there.

"The Turkish side during the talks in Ankara informed the Ukrainian delegation about the intention to apply similar measures against Ukrainian air carriers that fly to Istanbul from the airports of Ivano-Frankivsk and Dnipro. The dialogue on the issues related to the resumption of flights between the aviation authorities of both countries is continuing," the press service of the State Aviation Service of Ukraine told Interfax-Ukraine.

Dniproavia on October 20 announced the cancellation of flights from Dnipro to Istanbul during winter navigation because the Turkish side had not provided permits for the flights. Information about flights from Ivano-Frankivsk has not been received.

Earlier mass media reported Turkish Airlines could not fly to Ivano-Frankivsk and Dnipro because of the technical condition of runways at the airports of these cities, which caused certain restrictions on performing flights.
