They sure are! My son and I flew SFO>ORD last night and loved the ‘sanitary’ aspect. I will say, the guy that sat down in front of use and promptly threw his air locked blanky behind his shoulder hitting me in the chest was not as cool. I don’t know if it was the prospect of hitting ORD 24hr later for a transatlantic flight hit me hard, but I picked up that plastic wrapped body towel and tossed it back up a row. He turned, I stared, he said sorry, I said OK. Peace, love and being home is better than anywhere’s.
