Once you get to the glass doors to enter the airport building, have your Pre- registration forms in your hand, and tell the person at the door directing traffic that you have done the Pre-check. They will then put you in the line for Pre-check, families with children, residents, seniors, etc. That line gets priority with the immigration agents and they try to get it through as quickly as possible. Saturdays and Mondays are the busiest this time of year, and we don't know until the doors open if we will be using the finger printing method (biometrics) or the paper form. It all depends on how close together the planes land and if we have time to use the biometrics. You go through immigration ONE PERSON AT A TIME, unless you are handicapped and need assistance, or if you have children under age 12 with you. Even then, they want one adult with the kids. Please know where you are staying, how many days, etc. because they may ask you, and you can't be hollering at your wife in the other line to ask her where you are staying. There are people in orange vests there to help you with any questions you may have.
