The airline confirmed about the "incident" on flight BA422 which departed London's Heathrow at 3.10pm on Monday and landed in Valencia.
Passengers had to slide down emergency chutes to the runway, reported BBC.
Three passengers were taken to hospital and have since been discharged, the airline said.

A BBC editor, who was on the flight with her children, said that smoke filled the cabin "very quickly" about 10 minutes before its scheduled landing.
She said there had been no official announcement about what was happening as white smoke appeared to come through the air conditioning system into the cabin.
"Very quickly, you couldn't see the passengers two seats down from you."
