More airlines appear to have pulled back from flying over Ukraine after a U.S. warning that Russia could invade at any time, with flight insurance issues featuring in the background, and as a major European carrier announced a stop to overflights.
Monitoring of flight tracking service FlightRadar24 showed the airspace over eastern Ukraine nearly empty at 6:58 a.m. New York time on Feb. 14, with a strip of about 100 miles from the Ukraine–Russia border completely devoid of any flight traffic.
