I don't remember his name, but the gentleman who boarded us in Philadelphia went out of his way to find me a pen I could take on my flight. I wanted one so I cold do a puzzle in the magazine on the plane so I would not be bored. He was very nice.

Philadelphia airport is bad news, not easy to get around gate marked, not enough message boards.

Flight was fine but not excellent. Sat on runway in Philadelphia for a long time without any announcement. Luggage took forever to get off the plane.
