God, this is heartbreaking. That’s a lot of anxiety to deal with on top of the TRAVEL for WORK itself. I used to fly a lot…I’m a fitness model. I’ve never had an issue with a fat seatmate. I remember flying overseas to Germany with a very large man who kept his arms folded over his chest for the entire international flight…I always take the window to lean and sleep…I just curled up against it to give him more room, which he didn’t take. Now I know why.
I’ve honestly had more issues with bodybuilders than overweight people. They think a thigh and/or a shoulder in my seat area is ok.
I’ll happily sit next to someone heavy. A baby or toddler…not so much. There goes peace, quiet and sleep.
