Hartsfield-Jackson Atlanta International Airport liquids and security rules
Flying from Atlanta? Here is what Hartsfield-Jackson Atlanta International Airport states about liquids and electronics in hand luggage.
Atlanta applies the national TSA 3-1-1 rule: containers of 3.4 oz / 100 ml or less in one quart-sized clear bag. The airport's own advice is that it is TSA PreCheck members who may leave 3-1-1 liquids and laptops inside their bags, so expect to unpack both in a standard lane.
| Liquid container limit | 100 ml limit |
| Clear plastic bag needed | Yes |
| Liquids can stay in your bag | Not stated |
| Laptops can stay in your bag | No |
What this means at Hartsfield-Jackson Atlanta International Airport
- ATL describes TSA PreCheck as 'An expedited screening program that allows travelers to keep their shoes, belts and jackets on and leave their 3-1-1 compliant liquids and laptops in their bags.'
- ATL publishes no ounce/millilitre figures itself and says: 'For information on restricted items please visit the Transportation Security Administration website at www.tsa.gov.'
- CLEAR at ATL is described as 'a biometric-based program that allows passengers to enter dedicated security checkpoint lanes'.
- The ATL page covers REAL ID and TSA ConfirmID, and lists checkpoint hours.
- The ATL page does not mention CT or 3-D scanners, so whether any ATL lane lets liquids stay in the bag is not stated by the airport; TSA publishes no general CT exemption either.
- liquids_in_bag_allowed is null rather than false because ATL only states the PreCheck position and does not spell out the standard-lane requirement.
- Medications, breast milk, formula and baby food are exempt from the 3.4 oz limit under national TSA rules; declare them for separate screening.
