Tips to Get Through ATL Security Faster

1. Enroll in TSA PreCheck or CLEAR

 TSA PreCheck allows you to use expedited lanes and keep your shoes, laptop, and liquids in your bag. Wait times in the TSA PreCheck line at ATL are usually under 10 minutes.

CLEAR uses biometric scanning to verify your ID and skip ahead to the front of the TSA line—perfect for frequent flyers.

2. Know Your Terminal

ATL has two main security checkpoints:

• Main Security (Domestic Terminal): The busiest one.

• South Security Checkpoint: Typically serves Delta and can be less crowded.

• North Terminal Checkpoint: Often overlooked and sometimes has shorter lines.

3. Arrive Early

For domestic flights, arrive at least 2 hours early. For international flights, 3 hours is recommended.

4. Travel Light & Be Ready

Wear easy-to-remove shoes, keep your ID handy, and follow TSA's 3-1-1 liquid rule to avoid delays at screening.
