by far the fastest I got thru was when I reached last at 10:30AM on Jet Blue.........
only our plane had landed and it was just a matter of how fast you could walk thru immigrations, customs and out the door......
everyone basically just about waved us right thru.......

time before that I landed on Air Tran at like 1:15PM and it took the longest to get thru everything......what a nightmare

I would say anyone that lands in the morning is probably in the best shape.......or in the evening......
afternoons and the place get jammed big time........

and boy with that new terminal it's a haul with all that walking to get out of the airport........
