Whether you must remove liquids depends on the security technology at the specific airport. While the TSA's "3-1-1" rule—limiting liquids to 3.4oz containers in a single quart-sized bag—is still standard in 2026, many major airports have upgraded to CT (Computed Tomography) scanners. These advanced machines provide a 3D view of your bag, allowing you to leave liquids and laptops inside. However, at older checkpoints or smaller regional airports, you are still required to place your clear liquids bag in a separate bin for X-ray screening. Additionally, if you have TSA PreCheck, you generally do not have to remove your liquids regardless of the scanner type. It is always safest to pack your liquids near the top of your bag just in case you are asked to remove them by a security officer.
