If they could only predict who will be sitting next to you. I'm a window seat person, fairly close to the front of the plane. When I returned on Wed., a large man was seated next to me on the MoBay-Miami segment... there went half my seat. I was squished. It was torture. Due to a few people rearranging the rows so he & his wife could sit together, he moved to the row behind me, aisle seat. I could breathe again. I couldn't thank those folks enough. Thank God my next flight will be in 1st class (FF miles) so I don't have to deal w/ this again. It's rare anymore that I don't lose half my seat to my neighbor.
