A Swiss International Air Lines (SWISS) flight from Zurich to New York made an emergency landing at Bangor International Airport in Maine on Monday after smoke was reported inside the aircraft.

Flight LX14, operated by an Airbus A330 carrying 208 passengers and crew, landed safely at around noon local time after the crew declared an emergency. The aircraft had been en route to John F. Kennedy International Airport when it diverted to Bangor.

Smoke Reported in Business Class

According to SWISS, the diversion was prompted by smoke detected in the business class cabin. The U.S. Federal Aviation Administration (FAA) said the flight crew also reported a possible cockpit fire before landing.

Emergency crews were positioned at Bangor International Airport ahead of the aircraft’s arrival. After landing, local firefighters inspected the Airbus A330 but found no evidence of fire or excessive heat. The source of the smoke has not yet been determined.

Several passengers reported noticing an electrical odor during the flight, with one traveler suggesting it may have originated from a passenger seat.

Passengers Praise Crew’s Response

Passengers described the incident as frightening but praised the professionalism of the flight crew. They said the smoke lasted only a few minutes, oxygen masks were not deployed and the aircraft taxied normally after landing. No emergency evacuation was required.

The temporary runway closure at Bangor International Airport caused delays for other flights before normal operations resumed.

The incident is under investigation to determine the source of the smoke and whether any technical issues affected the aircraft during the flight.
