So I feel safe that on my trip in September from SXM to Sarasota via Atlanta which has a 3 hour layover won't be an issue. I am originally from New York and MANY years ago I had a part tie job chauffeuring a limo in New York City. The wait for the JFK international arrivals could be many hours waiting for the client to get through customs so I guess 3 hours should be safe. I thought that 3 hours was going to be close but based on these comments it seems it'll be a little quicker.
