Threats disrupt travel at two major airports

Apparent threats against planes disrupted travel at two major American airports Tuesday.

A bomb squad investigated a possible threat against a Delta Air Lines plane at George Bush Intercontinental Airport in Houston on Tuesday morning. No device was found on the plane and it later left the airport.

An airport spokesman did not provide a flight number to Reuters.

Later in the day, a flight from Houston to Los Angeles International Airport landed safely but was moved to a remote gate after an unknown threat, airport spokesman Charles Pannunzio said. Police, dogs and the Los Angeles Fire Department were sent to the scene.

The flight was Compass Airlines Flight 5931, the FBI said in a statement. Passengers left the plane by about 9:56 a.m. local time.

"While an assessment is always conducted following a threat, there is no known credible threat to the aircraft or passengers at this time," the FBI said.

The agency added the investigation into who made the threat is ongoing.

Pannunzio could not say if the threats on the two flights were related.

Correction: A possible threat was made at George Bush Intercontinental Airport in Houston. An earlier version misstated the airport's name.
