Following the 2014 Crimean crisis pro-Russian militia forces took control of the airport on 28 February 2014. Crimean airspace was closed and air traffic was disrupted for two days. On 11 March, Russian forces took over the control tower and closed Crimean airspace until the end of week. Ukraine International Flight PS65 was denied landing and diverted to Kyiv. With the Russian Takeover of the Airport, the International Civil Aviation Organization (ICAO) expressed concerns about the safety of international flights in the region and recommended airlines to avoid Crimean airspace. By the same token on 3 March 2014, the European Organisation for the Safety of Air Navigation (Eurocontrol), who also did not recognize the unilateral takeover of Ukrainian airspace by another country, had confirmed that the majority of transitional air routes have been closed, in accordance with the Chicago Convention. Ukrainian airlines also suspended routes to Simferopol.
