Full review at loungeindex.com/NAmerica/USA/P... from loungeindex.com
The American Airlines Philadelphia Business Class lounge is OK, if not spectatular. Of the four AA lounges at PHL, it is by far the best, big, bright, airy, recently renovated, and with a great view of the gates on one side, and the marketplace on the other. There is a decent bar, but only snacks.
