Thanks for the welcome! I am glad I found this forum since we travel alot. This is our first time ever clearing customs in JFK though.
Yes we are US citizens
Will will have nothing to declare
Out luggage will be checked, but talked with Air Jamaica and they will process it to go all the way home to Columbus, but I realize that we will need to pick it up for customs. If this will make it harder to make the connection we could try 2 carryons.
