Port Authority officials cleared the terminal as a precaution after a worker reported a smoking package on a luggage ramp. The handler reportedly said the baggage seemed warm.
The package never made it onto the plane, a Delta aircraft which was headed to Richmond, Va., and the plane was brought back to the gate for evacuation. The plane was then moved to a remote location.
Employees were allowed back into the building around 12:30, with passengers expected to follow.
