A London flight to Philadelphia has been diverted to Dublin after reports of a “chemical spillage” on board.
American Airlines said two crew members and one passenger on board flight AA729 were taken to hospital “for evaluation” after it landed at 13:15 GMT.
It added that the plane had landed due to an odour “caused by a spilled cleaning solution in the galley.”
One passenger wrote on Twitter that the spillage “led to sickness outbreak and an emergency landing”.
A spokeswoman for Dublin Airport said the flight was diverted “for a medical emergency”.
“As per standard operating procedures there was a full turn-out of Dublin Airport’s emergency fire services,” she added.
