I have a 1 hour and 40 min layover at DTW (flying Delta). I'll be coming from Manila and will take a connecting flight to New York, also on Delta. I know I don't have much time to clear customs and go through immigrations, with that time. Could anyone advise me on how to navigate the airport? I'll be carrying three huge bags plus carry on, and i'm a 100 pound person who has never flown before, plus I have very little knowledge of airports.
