Sounds like the same guy who sat next to me a couple years ago on a flight on Frontier from Denver to Indy. Frontier has assigned seating, and I had an aisle seat. There was a slightly large lady in the window seat. The plane was almost ready to leave, and this huge guy gets on all in a sweaty fluster and takes the seat next to me. It was good I was sitting down first He was sort of on top of me on for the entire flight. I joke that when the plane hit some turbulence I didn't flop around like I usually do. I was cold on the first leg of the flight from SNA to Denver, but this guy solved that problem. I suppose I could have asked to get a different flight, but, it was a business trip, the last flight back to Indy, which isn't served well by Frontier, Sunday afternoon, and I had to get to work on Monday morning.
