ATL: The World's Busiest Airport

Why TSA Wait Times at ATL Vary So Much

Several factors impact how long you’ll be standing in line:

• Time of Day: Early mornings and late afternoons tend to be busiest.

• Day of the Week: Mondays and Fridays are high-traffic due to business and leisure travelers.

• Season: Holidays and summer months see huge spikes in passenger numbers.

• Terminal & Airline: Delta passengers often crowd the South Terminal, while international flyers go through Concourse F.

Knowing this helps you adjust your schedule and expectations accordingly.

A Personal Story: The Morning Rush at ATL

Let me tell you about Jasmine. She had a 7:45 AM flight to Miami on a Friday. She figured arriving at 6:15 would be plenty early. When she got to the TSA checkpoint at the Main Terminal, she saw a wall of people, zigzagging lines, and heard TSA agents shouting about liquids and laptops.

The wait time? 48 minutes. Jasmine didn’t have PreCheck or CLEAR, and she missed boarding by the time she reached the gate.

Her story isn’t uncommon. But yours doesn’t have to end the same way.

• Accessible to all passengers.

• Open 24/7.

✈️ North Checkpoint

• Less crowded at times.

• Great for Delta passengers.

• Often preferred by frequent flyers.

✈️ South Checkpoint

• Another hub for Delta.

• Offers TSA PreCheck and CLEAR.
