South Korea airlines say flights over Ukraine rerouted since March

SEOUL (Reuters) - South Korea's two major airlines said on Friday they had stopped flying over Ukraine air space since March 3 because of security concerns. Korean Air Lines Co Ltd and Asiana Airlines Inc both said they had changed flight paths to avoid flying over Ukraine since the same date. A Malaysia Airline System Bhd (MAS) plane was brought down in eastern Ukraine on Thursday, killing all 298 people on board, in what the United States said was probably a ground-launched missile strike.
