Flying from Hartsfield-Jackson Atlanta International? The verdict, the airport's own wording and its source link are below. Checked 20 September 2026 against the airport's own website. Same rules for hand luggage and carry-on.
Last checked: 20 September 2026, against the airport's own page.
What changed: Atlanta follows the national TSA 3-1-1 rule. This page records the airport's and TSA's wording as last checked and has not been re-verified since.
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.

| 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.
- We show whether liquids can stay in the bag as 'Not stated' 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.
- TSA (tsa.gov, checked 15 October 2026): travel-sized containers are limited to 3.4 oz (100 ml) or less per item. At security lanes with CT scanners, TSA says passengers do not need to remove their travel-sized liquids (TSA release, 13 July 2026). CT lanes are rolling out lane by lane, so check the signs at your checkpoint.

Flying home? Liquids rules belong to the airport you leave from, not the one you started at. GOV.UK (UK guidance) advises checking the rules at your departure airport, any airports you pass through and your return journey, because airports differ.
