The CLEAR lane entrance at the Atlanta airport checkpoint

CLEAR’s own page lists lanes at three places, Domestic Terminal North, Domestic Terminal South and the International Terminal, each with a different mix. Our [TSA Clear page](https://atlairportguide.com/venues/tsa-clear/) lists it in the Domestic Terminal. ATL’s own security table shows CLEAR at Lower North and South only. ATL says the busiest times usually fall between 5 a.m. and 9 a.m., so the early lanes are the ones worth knowing.

## Which lane each checkpoint has

| Checkpoint | CLEAR lane | CLEAR’s lane hours | ATL’s listed hours |
| --- | --- | --- | --- |
| Domestic Terminal Lower North | Standard | 4:30 a.m. to 7:30 p.m. | 3:30 a.m. to 9 p.m. |
| Domestic Terminal South | TSA PreCheck | 4:30 a.m. to 9 p.m. | 4 a.m. to 9 p.m. |
| International Terminal | Standard | 5 a.m. to 7:30 p.m. | 4:30 a.m. to midnight |
| International Terminal | TSA PreCheck | 5 a.m. to 7:30 p.m. | 7 a.m. to 10 a.m. and 2 p.m. to 7 p.m. |

At Lower North, South and the International standard lane, the CLEAR lane keeps shorter hours than the checkpoint. A lane can be closed while the checkpoint is open, so if you arrive in the gap you’ll use the regular line.

The Domestic Terminal Main checkpoint is open 24 hours, and CLEAR doesn’t list a lane there. Every checkpoint’s hours are on the [security page](https://atlairportguide.com/security/).

## Which checkpoint to pick

ATL says passengers can reach all concourses and gates from any checkpoint, so choose by lane and not by gate.

- **CLEAR without PreCheck, flying domestic.** Use Lower North, which CLEAR’s page calls Domestic Terminal North. ATL lists no CLEAR lane at the North checkpoint, and CLEAR doesn’t list a standard lane at South, only a PreCheck lane that ATL names CLEAR w/ PreCheck.
- **CLEAR with PreCheck, flying domestic.** South has the lane built for both, and it stays open until 9 p.m. Our [CLEAR Plus with TSA Pre listing](https://atlairportguide.com/venues/clear-plus-with-tsa-pre/) places it in the Domestic Terminal without naming a checkpoint or a lane.
- **Flying from the International Terminal.** CLEAR lists both its lanes there at 5 a.m. to 7:30 p.m. ATL’s table lists two windows beside its PreCheck row, 7 to 10 a.m. and 2 to 7 p.m., while CLEAR’s page gives its PreCheck lane 5 a.m. to 7:30 p.m.
- **Arriving before the lane opens.** ATL lists the Main checkpoint as the only domestic one open 24 hours, and says hours can change.

## How to enroll in CLEAR and PreCheck

You can enroll on CLEAR’s website. ATL also lists CLEAR enrollment pods in the Domestic Terminal, North and South, near the Main Security Checkpoint. ATL describes CLEAR Plus as a biometric program that lets passengers enter dedicated security lanes. It describes TSA PreCheck as an expedited screening program that lets you keep shoes, belts and jackets on. CLEAR’s page lists its enrollment point on the departures level of the North side, near the checkpoint entrance, with CLEAR Plus hours of 4:30 a.m. to 8 p.m. and TSA PreCheck hours of 6 a.m. to 8 p.m. CLEAR also offers TSA PreCheck pre-enrollment, with the application finished at the airport, though the same page says CLEAR’s PreCheck enrollment is planning to open on 6/25.
