Delta flight DL251 had left Barcelona for Boston Logan International Airport when the smoke was spotted on board. The Airbus A330, carrying 296 passengers, was diverted to Porto in northern Portugal, where it made an emergency landing. Flight data showed the flight had left the Catalan capital at 3.15pm on Sunday. But a mechanical issue was reported about two and a half hours after takeoff. A total of 14 passengers reportedly inhaled smoke, with eight treated on the ground at Francisco Sá Carneiro Airport in Porto.
