Got back a couple weeks ago & just wanted to share my experience with the kiosks..... Was by far the quickest I have ever gotten in/out of the airport. As I walked into the customs area the lines were totally packed - I showed my form & passport expecting to be directed to the end of one of the long lines, but to my surprise they directed me all the way to left wall where the kiosk's are - no wait at all...was simple and soo fast. From landing to outside with my luggage was seriously like 30 minutes! I still don't know why so many people had to stand in those long lines while others were directed to the kiosks, but my best guess is the country you are arriving from.
