Every time the flu was going around I would come down with it after a plane ride. Unlike other transportation there isn't a good exchange of outside air. It probably should have been looked at before this but there has to be something other than masks that can make the space safer for travel.
I've gotten sick so many times after flights. Masks suck but on a plane is the one place I'll gladly wear one.
The more memorable ones:
-Only time in my entire life that I can remember getting a stomach bug that caused me to throw up was the day after a flight back from San Antonio. I spent as much time in the bathroom over the next 2-3 days as I did in the bed.
-One of the few times I've had the flu, came down with it during a week long trip to Salt Lake. Those were some of the most miserable feeling days of my life, being that sick and away from home.
-Last fight I took before covid really set in, first week of March 2020, the lady next to me was coughing her head off the entire flight. She joked "I swear it's not the china virus". 3-4 days later I'm running a fever and figured I had it. Pretty sure it wasn't covid but no doubt that lady made me sick.
