Airport authorities and police rushed to an airplane arriving from Moscow at the John F. Kennedy International Airport after reports of a bomb on board.
Port Authority police confirmed that they investigated after they received a call.
The Aeroflot aircraft landed at JFK late Sunday. Authorities boarded the plane after passengers had disembarked and swept it for explosives.
Around 250 passengers and crew were on board. JFK personnel described the situation as an "ongoing incident."
Airport authorities said all other operations were unaffected and the facility was operating normally. Other flights remained on time and there were no delays.
"Due to an ongoing incident, emergency personnel and activity may be observed at #JFK airport. Please note that the airport is fully open and flights are operating without delays," JFK posted on its official Twitter account.
According to sources familiar with the airport's operations, the flight was a Boeing 777-300ER labeled Aeroflot flight SU102. The aircraft departed Moscow the same day.
Police are still trying to identify who called in the bomb threat.
Passenger traffic at the airport, considered to be one of the busiest in the country, has yet to return to pre-pandemic levels. Given the slump in demand, airport authorities have delayed their $3.8 billion plan to refurbish the facility.
The Port Authority of New York and New Jersey, which runs the airport, previously said that it was still waiting for a response to its request for federal aid.
Airport development relies on funding from airlines and private terminal operators. With airlines and air transport contractors still struggling, airport operators have mostly scaled down their projects.
According to a report published by Moody's Investors Service, gateway airports - such as JFK - are expected to recover more slowly than smaller airports.
