But the pre-check lane is so much faster that it's the one you want to use if you have a choice. I think they can do 2-3 passengers in the time it takes the flagship lane to do one. Part of this is leaving laptops, liquids, etc. in your carry-on and leaving belts and shoes on. Part of it is also using the metal detector instead of the scanner where you have to stop and hold your arms up or out and wait.
