Common questions about security
Which security line is fastest?
This guide does not publish wait times, its own or anyone's estimate, and the airport's records do not say which line is faster on average. What the records do let you choose by is the hours above and the lanes: PreCheck Touchless ID at South Checkpoint. Each is for eligible travelers only.
How early should I get to security?
Of the 3 checkpoints that publish daily hours, the earliest to open is Lower North Checkpoint, at 3:30 a.m. Among them, the last to close is North Checkpoint, Lower North Checkpoint and South Checkpoint, at 9 p.m. Check that the checkpoint for your gate is open at your time: they do not open and close together.
Is TSA PreCheck at every checkpoint?
The airport states TSA PreCheck at South Checkpoint and International Main Checkpoint. Its text for Main Checkpoint, North Checkpoint and Lower North Checkpoint does not state PreCheck. That is not the same as saying it is missing, so check the airport's checkpoint map or the TSA before you plan around it.
Where is PreCheck Touchless ID?
South Checkpoint. It is for PreCheck members who opt in through the airline's app or profile, and no ID or boarding pass is shown at the lane.
