Military jets escort NYC-bound flight
A New York-bound plane from Los Angeles safely landed after some passengers who were apparently going in and out of the bathroom raised concern.
Two military jets escorted the American Airlines flight. A law enforcement official said it wasn't thought to be terrorism.
The North American Aerospace Defense Command scrambled two F-16 jets to shadow Flight 34 for about 100 miles until it landed safely at New York's John F. Kennedy International Airport shortly after 4 p.m., the Transportation Security Administration said in a statement.
ABC News reported that multiple passengers were moving in and out of the bathroom, while a NORAD spokesman said the passengers locked themselves in the bathroom and were still inside when the plane landed.
Federal Air Marshals aboard the flight were able to resolve the incident when the passengers complied with their instructions, police officials said. The pilot then reported via radio that the situation was under control, reported ABC News.
The New York Police Department and the FBI Joint Terrorism Task force were monitoring the incident in case additional resources were needed.
Authorities with the FBI and Port Authority Police met the flight when it landed. The three passengers involved were released without charges after being interviewed.
The exact reason behind the passengers' behavior was unknown.

Earlier, on a Denver-to-Detroit Frontier Airlines flight, the crew reported that two people were spending "an extraordinarily long time" in a bathroom, Frontier spokesman Peter Kowalchuck said.
NORAD sent two F-16 jets to shadow the plane with 116 passengers until it landed safely.
When the plane landed without incident at Detroit's Metropolitan Airport, police detained three passengers - two men and a woman - but were released after questioning.
The plane was searched and nothing was found, the FBI said.
The flight originated in San Diego before stopping at Denver International Airport on its way to Detroit.
