Russian Prime Minister Dmitry Medvedev has instructed the Transportation Ministry to consider retaliatory restrictive measures against Ukraine for banning Russian flights.
Russian government spokeswoman Natalia Timakova made the announcement on September 28.
The Ukrainian government said last week that it was banning flights by Russian airlines, primarily Aeroflot and Transaero, to Ukraine starting October 1.
Prime Minister Arseniy Yatsenyuk said on September 25 that Russian transit flights to Ukraine will still be allowed unless they contain military equipment or military personnel.
Earlier this month, Kyiv blacklisted 25 Russian aviation companies as threats to its national security.
Kyiv-Moscow relations are extremely poor due to Russia's annexation of Ukraine's Crimea peninsula in March 2014 and support for pro-Russian separatists in Ukraine's eastern regions of Luhansk and Donetsk.
