We are flying to LGA and get in at 7:40 AM on the Wednesday before Thanksgiving. We then fly out of JFK at 3:40 PM on an international flight. We already planned on taking a taxi between airports. However, that's a lot of time to kill at the aiport. We will each have a backpack as a carry on and a larger bag to check for luggage. Any ideas of what we can do with that time?
