Last year I was flying back from LAS-JFK in F, I set next to a guy who soiled himself and had his brownies stained through his khakis. He asked me to switch seats with him because he had to go back and froth to his kids in the back. Thank God for leather seats, I drained my water glass and used to blankets to wipe the smell off. But still smelled and I could not tell this poor guy his browny tales.
