A GLASGOW woman who was a passenger on a British Airways flight to Valencia that filled with smoke mid-air has revealed she is still experiencing breathing difficulties two months on. 

Gayle Fitzpatrick, 40, told the BBC that she gets breathless walking up-hill following the incident which happened in August. 

She said: "I don't smoke, I've never had any health concerns. So I know [it] must be directly attributable to that flight and whatever I inhaled."

British Airways, who could not comment for legal reasons, are waiting for the outcome of a Spanish accident investigation which will look at why the cabin of flight BA422 filled with spoke shortly before landing.

Gayle has, however,  now been referred to a respiratory specialist.

She was one of 175 passengers and eight crews forced to evacuate the plane via inflatable slides after it touched down in Spain.

In a statement, British Airways said it would never operate an aircraft if it believed "it posed any health or safety risk to customers or crew".

The airline added it supported customers after the incident and it continues to offer "ongoing help and support."

The airline said: "We are legally unable to comment on causes until the Spanish air accident investigation is concluded."

Gayle, who was with her husband Stephen when the incident happened, previously said: "It was very scary. The flight was just ending, and with 10 minutes to go the flight started descending rapidly as smoke started to fill the cabin.

"A detector was going off saying the cabin was filling with smoke. It was like a horrible white acrid smoke.

"There was chat it was an air conditioning unit. There were no communications from the crew, some of which started to wear full oxygen masks and protective fire wear.

"Eventually they managed to open the emergency doors and told us to go down the chutes.

"There were fire engines waiting and then we were all ushered into a bus then to the airport.

"We are still waiting to hear what happened. People were crying and hyperventilating. It was genuinely scary."

She added: "We were not told it was an emergency until we had landed and they were trying to open the cabin doors for passengers to jump down the chutes."
