I'm off to Detroit in June for a month to see my Girlfriend. The only problem I have is that I'm flying from Manchester to Philadelphia landing at Terminal A my connecting flight to Detroit Wayne County is at Terminal F. I have an hour and a half to clear customs.
This is my first time in the US how long will it take to clear customs? I have heard all sorts of horrible things about Philly Airport. Is an hour and half enough? I booked it through Expedia and the carrier is US Airlines.
