Preliminarily planning a belated 50th Anniversary Trip 3 years later from Phila, PA to Crete for late August/ early September and trying to find the "best connections". Length of stay at least 8 - 10 days, depending on the connections. So far I see PHL to ATH is 9 1/2 hours, ATH to Crete is 50 minutes. PHL to London is 6+ hours, London to Crete 5+ hours. While total times are within a couple of hours of each other, also trying to factor in the wear & tear on these ole bods. Will be using American Airline miles so that will restrict carriers. Would appreciate any suggesttions/recommendations from anyone that's made this trek. Thank you in advance!
