I am traveling to Israel for the first time with a tour group. The experienced group leader has told me that he is concerned that if I leave JFK during our 11 hour layover, there could be some potential security implications with El Al. Also, he believes that I might have trouble checking back in to the airport as "my boarding pass will not be issued until three hours before flight departure" according to him.
I don't NEED to leave the airport, but it seems like if I can, there is plenty to do in NYC instead of sitting in the airport.
On a related side note, if I am flying AA to JFK, will I need to claim my checked luggage from AA and recheck it with El Al? Or will AA check it all the way through?
Thanks for any insight.
