True; it's easy to forget that lots of people go to the airport and back every day, and not to catch a plane. And many business travelers are on a one-day out-and-back trip and may be carrying nothing but a briefcase and a laptop. In any case, many airport rail services sacrifice a little onboard space for luggage. Connections with the 102 at 69th St. and Drexel Hill Jct. would open up a lot of the western suburbs to the airport without going through Center City.
