I'm flying from Düsseldorf to JFK on Air Berlin on a Thursday afternoon, arriving at JFK at 15:50. My next flight (different airline, different ticket) is with US Airways from JFK to Charlotte at 18:15. Is 2.5 hours enough time to clear customs and get to the US Airways terminal? I'm a US citizen and I'm not checking any bags. Your advice will be much appreciated!
