Yes, you can bring a fanny pack through TSA, but how you handle it depends on the security equipment at the checkpoint. In 2026, many airports use Advanced Imaging Technology (AIT) or millimetre wave scanners; if you are wearing the fanny pack, you will likely be asked to remove it and place it in a bin for X-ray screening to prevent "alarms" on the body scanner. If you are using a newer "Computed Tomography" (CT) scanner, you can often leave it inside your carry-on bag, but not on your body. From an airline perspective, a fanny pack is usually considered part of your "personal item" quota. While some gate agents ignore small waist bags, stricter budget carriers may insist that it be tucked inside your backpack or purse if you have already reached your two-bag limit. A pro-tip for 2026 travelers is to wear the fanny pack under a jacket during boarding to avoid it being counted as an extra "bag," though you must always remove it for the TSA scan to ensure a smooth security experience.
