Bomb threats against U.S. airlines

Multiple bomb threats are made against U.S. airlines in five major cities. Government sources:

The TSA Operations Center in Washington, DC had received a phone threat stating that there was an explosive device on the plane, [flight from San Diego to Philadelphia]. Out of an abundance of caution the airport declared a bomb threat and moved the plane to a remote area. In addition to the U.S. Airways flight, threats were made on a Delta flight to Atlanta, a United flight to Chicago O’Hare, a Korean Air flight to San Francisco and a Volaris Air flight to Guadalajara, Mexico, according to government sources.
