Korean Air faces the prospect that its deal to acquire indebted Asiana Airlines could fall apart over U.S. and European Union concerns about reduced competition on certain cargo routes.
The U.S. Department of Justice is considering legal action to stop the merger because of concern the combined airline would dominate routes to the U.S. that they currently compete on for passenger and cargo traffic, according to reporting by Politico.
Both airlines fly to San Francisco, Los Angeles, Seattle, New York City and Honolulu.
