Hi All! I just booked Antarctica for Jan 2027 and am looking at flights. I am looking at Delta and would fly from Boston with a 3hr44min layover in Miami. My question is for the return flight home from Buenos Aires to Boston. The best option would be to return via JFK and the 2 layover options are either 2hr29mins or 5hrs. Could I make my connection in 2.5 hrs?? I have never been to the JFK airport or connected through there. Also, I would be in business class. Thanks so much!!!
