Got off the plane (gate D21, if I recall) and pretty much walked all around the airport to get to Immigration. Of course, the queues at Immigration were nightmarishly long and I was happy for the opportunity to test the USCIS CBP kiosks. The first bank of kiosks I saw were "out of service" and my heart sank, since, as I mentioned, the queues were horrendous. Fortunately, I saw a second bank of kiosks about ten feet away and they were available - not one person in line to use them! It took me less than twenty seconds to authenticate myself and pull up my APIS info. Biometric identification and CBP questions (no more forms, yay!) took a few seconds longer and then I got my Customs Clearance ticket!
It was smooth sailing past the crowds via a dedicated lane all the way to the baggage carousels. Zoom zoom zoom. Got my bags and handed my Customs Clearance ticket to the CBP Officer on my way out. Best thing that can happen to a frequent traveler. Well done, CBP! Thank you!
