A plane was evacuated at Kennedy International Airport on Sunday amid an investigation into a bomb threat, the authorities said.

The Port Authority of New York and New Jersey, which operates the airport, said the flight, American Airlines Flight 67, had originated in Barcelona. More than 200 people were onboard, including crew members, said a Port Authority spokesman, Joseph Pentangelo.

The threat, he said, had been delivered by telephone and the evacuation began before 1 p.m.

Shortly after 2 p.m., Mr. Pentangelo said the authorities had found no evidence of any danger after inspecting the plane, including the cargo area.

The episode was being investigated by the Port Authority Police Department, the New York Police Department and the Federal Bureau of Investigation, Mr. Pentangelo said.
