CHICAGO (WLS) -- The Federal Aviation Administration is investigating after a flight from San Francisco to Boston was diverted to Chicago O'Hare International Airport on Friday morning.
Through the heavy fog, ABC7 cameras could see some people getting off the plane at O'Hare.
The crew on JetBlue Flight 734 reported an odor in the cabin, and the Airbus A321 landed safely around 3 a.m., the FAA said.
Officials did not immediately provide further information.
