I’m a plus sized traveler as i’m 6-foot-2 9only about 210 pounds mind you). I demand an extra comfort seat for free very time i fly!!!
I’m 6’3” and about 260. I get either an aisle or window seat, and make sure ido not intrude even an inch into the space of those sitting next to me. I have muscular legs, so that helps.
I was once assigned to a middle seat between two ginormous women. Walked back to the front of the plane to discuss the situation with a flight attendant. She took one glance and then gave me a seat in first class.
