So I flew from DFW on the 31st via Heathrow to Bologna. When the flight was just about to taxi the announcement came on that they would be spaying the cabin for disease prevention. I can’t swear that was the exact term but it was close. The flight attendant then walked up and down the aisle twice spraying a medium aerosol can into the air. We were assured it was safe and to close your eyes if you wear contacts. Several of us looked at each other like WTF!!?? Other people were very blasé, like it wasn’t new. I asked a flight attendant how long this was happening on BA flights and she said it’s been at least a couple of months she thought, and ‘only on flights to Italy and maybe India’.
You could definitely see it hanging in the air but there was a very light smell. Has anyone any information on this?
