As the world’s busiest airport, Hartsfield-Jackson Atlanta International Airport (ATL) is a central hub for both domestic and international travelers. With tens of millions of passengers passing through each year, navigating ATL can be overwhelming—especially when it comes to security wait times. Whether you’re a seasoned flyer or a first-time visitor, understanding the security process and planning accordingly can help minimize stress and ensure a smooth journey.
This comprehensive guide will explore everything you need to know about ATL Security Wait Times including peak travel periods, TSA PreCheck benefits, tips for faster clearance, and the best times to arrive at the airport.
Overview of ATL's Layout and Security Checkpoints
ATL operates two main terminals—Domestic and International (Concourse F)—and is organized around seven concourses (T, A, B, C, D, E, and F). For domestic travelers, the primary security checkpoints are:
- Main Checkpoint: Located between North and South Terminals, accessible to all domestic passengers.
- North Checkpoint: Often used by Delta Air Lines passengers, especially those with Sky Priority or TSA PreCheck.
- South Checkpoint: Typically used by other airlines, including Southwest and American.
- International Terminal Checkpoint: Located in Concourse F for travelers flying abroad.
Security checkpoint options are determined by your airline and ticket class, though all gates are accessible from any checkpoint once you clear security.
Average ATL Security Wait Times
Hartsfield-Jackson typically ranks well in terms of security efficiency for a high-traffic airport. However, wait times can vary widely based on several factors, including the day of the week, time of day, holidays, and airline-specific traffic.
- Average wait time: 15 to 30 minutes
- Peak periods: 6:00 AM to 9:00 AM and 3:00 PM to 6:00 PM
- Least busy times: Late evenings (after 7:30 PM) and midday (10:00 AM to 1:00 PM)
During holiday seasons and major travel days (such as the Wednesday before Thanksgiving or the Sunday after), wait times can easily exceed 45 minutes. ATL recommends travelers arrive at least 2 hours early for domestic flights and 3 hours early for international flights to avoid delays at security.
TSA PreCheck and CLEAR at ATL
To expedite security processing, ATL offers access to both TSA PreCheck and CLEAR, two programs designed to reduce wait times significantly.
TSA PreCheck
Available at North and South checkpoints, TSA PreCheck offers a streamlined security experience. Travelers with PreCheck can:
- Use dedicated lanes
- Keep shoes, belts, and light jackets on
- Leave laptops and liquids in carry-on bags
PreCheck lines at ATL generally move faster, with average wait times under 10 minutes—even during peak hours.
CLEAR
CLEAR is available at all domestic checkpoints and uses biometric verification (fingerprint or eye scan) to confirm your identity. Once cleared, users proceed directly to physical screening—bypassing the ID check.
- Annual Fee: Around $189 (discounts available for Delta SkyMiles and United MileagePlus members)
- Best for: Frequent travelers and business passengers looking to skip lines consistently
Both programs are compatible, meaning travelers with CLEAR and TSA PreCheck benefit from the fastest possible route through security.
Real-Time Security Updates
One of the best ways to monitor wait times at ATL is through:
- Hartsfield-Jackson’s official website: They occasionally post estimated wait times.
- MyTSA App: Provided by the Transportation Security Administration, this app offers real-time updates and crowd-sourced data on current wait times.
- FlightAware or airline apps: Some carriers include security wait time estimates within their mobile platforms.
Being proactive and checking current wait times before leaving for the airport allows travelers to make informed decisions about when to arrive.
Tips to Shorten Your Time at ATL Security
Even without TSA PreCheck or CLEAR, there are several ways to streamline your experience at ATL security checkpoints:
- Check Your Terminal: Make sure you know whether you’re departing from the Domestic or International Terminal to avoid unnecessary walking or shuttle rides.
- Pack Smart: Follow TSA’s 3-1-1 rule for liquids (3.4 ounces max, in a quart-sized bag), and avoid packing prohibited items. Place laptops and electronics in easily accessible spots.
- Dress for Efficiency: Wear slip-on shoes and avoid excess metal (belts, jewelry) to ease the screening process.
- Travel Light: Carrying fewer bags can help you pass through more quickly.
- Arrive Early: Always allow extra time—especially during high-traffic seasons like summer, Thanksgiving, and winter holidays.
- Use Mobile Boarding Passes: Download your boarding pass on your smartphone to reduce time spent at kiosks or check-in counters.
- Families and Special Needs: ATL offers a family lane and assistance for travelers with disabilities or medical conditions. Inform TSA agents in advance if you need help.
International Travelers and ATL Security
For those departing from the International Terminal (Concourse F), the process involves both security and customs checks. Unlike domestic terminals, this area tends to be less crowded, though international flights often involve larger aircraft and more passengers per departure.
- Arrive 3 hours before flight time
- Check visa and passport requirements in advance
- Consider using Global Entry for expedited re-entry into the U.S.
International travelers benefit from many of the same expedited options as domestic passengers but should still build in ample time due to passport checks and longer screening lines.
Accessibility and Customer Support
ATL offers support for travelers who need special accommodations. Passengers requiring assistance with security screening should:
- Notify their airline in advance
- Contact TSA Cares (72 hours before travel) at 1-855-787-2227
- Use ATL’s wheelchair and customer service desks located near entrance areas
The airport is ADA-compliant and provides clear signage and trained staff to help ease the process.
Recent Improvements and Innovations
To manage high passenger volumes more efficiently, ATL has introduced several improvements:
- Automated Screening Lanes: These help multiple passengers load bins simultaneously, speeding up the process.
- Facial Recognition Technology: In select lanes, this reduces the time needed for document verification.
- Expanded CLEAR Lanes: With increased demand, ATL has added more locations and staff to streamline the experience.
These investments aim to improve throughput, decrease wait times, and enhance passenger satisfaction.
