It is probably a three class plane sold as a two class plane for the domestic segment. They do that quite often into Miami. I used to like to take the 777 to Miami as some of their flights were two class in a three class plane which meant you got the sleeper seats.
Last time I did that though they used the Pacific instead of the European plane so the seats reclined into beds but were not the barcalounger swivel seat that is really cool! Alfred--
