I'm flying Atlanta - JFK - Stockholm, Sweden with Delta and I only have an 1 hour layover in New York. I just want to make sure I will not have to go through customs when i arrive at JFK & that my bags will be checked all the way to Stockholm (since I only have one hour)?
Of course, you do not go through customs when LEAVING the US. Immigrations and custom will occur in Stockholm. However, on your return you go through US customs and immigration the first time you hit the US. That could be JFK. Plan on three, four hours. When you return you claim your bags for customs and then recheck your bags on to Atlanta. You bags will be check through to Stockholm on the out bound trip.
