I took my first flight a couple of weeks ago to L.A. on American connecting through DFW. In my case both my outbound and return flights were relatively full but a few of us managed to be lucky enough to move around and open up the middle seats. Honestly the only difference to my travel routine was wearing a mask which I didn't mind at all. I was a habitual seat and tray table wiper with Clorox wipes long before COVID. I've always had a stockpile of them because I travel so much so when they disappeared from the stores I was blessed to have some.
