I am arriving with Air France or Lufthansa from Europe, then connecting at Terminal 1 to Korean Air flight to Korea. Assuming I have no luggage, can I transfer in 60 min. With AF, i have 65min lay over, and with Lufthansa 75min. Must I go through immigration or simply proceed to transfer desk at arrival? If I use non skyteam flight (LF) I can not get boarding pass in Europe, therefore only possible to get in JFK.
Tight Transfer time at JFK
