We are looking at airfare right now and can save about $30 per ticket to fly home through Philadelphia rather than Charlotte via US Airways. We've usually flown through Charlotte and know Customs there is pretty harmless. How is Customs in Philadelphia for our return flight home? Is it worth the $60 we will save? It also means leaving 1/2 hour earlier from the resort and getting into Chicago 1/2 hour later too, which isn't too big of a deal.
