Outbound to Jamaica I had 50 minutes between flights and made it just fine. The gate service person was able to give me directions to the train and it was quick. I had time to spare. They were offering to check bags free at the gate to increase the overhead bin room.
Upon returning this past Saturday the new area is nice and it didn't take long to go through customs once the luggage arrived.

There was confusion as the de-plane information stated that you couldn't put your duty free liquids in your ongoing carryon bag, but the overhead recording at the international baggage area stated not to open your luggage before going through customs. Some people were placing rum bottles in their suitcases anyway.

The checked luggage "re-check" area was easy. Then the re-scan for DHS, they could have used a couple more stations, still didn't take too long.
