On May 25, 2021 we were on our flight from Punta Gorda, Florida to Dayton, Ohio. I understand the regulation to wear mask throughout the flight to protect from the COVID virus. What I don’t understand is the dirt and grim all over the surfaces that could harvest the COVID virus. I didn’t pack my germ detector but I can assume that a virus can survive on unsanitary surfaces . Row 12, seats D, E and F.
