New Airport Scanners Force Passengers to Check Overpacked Carry-On Bags
Washington, Wednesday, 23 September 2026.
Updated airport 3D scanners feature smaller openings, forcing travelers with overstuffed carry-on bags to check them, despite removing the requirement to unload liquids and electronics.
Travel Disruptions at Security Checkpoints
Travelers across United States airports are encountering unexpected delays as the Transportation Security Administration implements updated screening protocols in September 2026 [1][2]. The operational shift requires passengers with oversized or densely packed carry-on luggage to check their bags, impacting business travel schedules and airline baggage handling logistics nationwide [1][2]. This change stems from the deployment of new three-dimensional computerized tomography scanners at security checkpoints [1][2].
Scanner Dimensions and Restrictions
The new CT scanners feature an opening nearly 2.54 cm smaller than previous models, potentially forcing passengers with larger or expandable carry-on bags to check their luggage [1][2]. While the standard airline carry-on allowance remains 55.88 cm x 35.56 cm x 22.86 cm, which technically fits within the new scanner dimensions, overstuffed items may exceed the narrower opening [1][2]. TSA spokesperson Daniel Velez stated the design is necessary to accommodate the advanced imaging technology and guarantee optimal performance [1][2].
Economic and Logistical Implications
Unlike previous screening systems, the new CT scanners require every item to be placed flat inside a checkpoint bin, altering the flow of security lines [2]. However, the technology allows passengers to leave laptops inside their carry-on bags and removes the requirement to separate travel-size liquids for screening, aiming to minimize manual inspections [1][2]. The implementation is expected to decrease the frequency of manual bag inspections despite the initial sizing constraints [2].
Emerging Guidelines and Future Considerations
On 15 September 2026, the TSA issued new guidelines regarding the packing of toys containing gel-like liquids, known as squishies, which have been subject to confiscation at security checkpoints [1][2]. Additionally, the agency is considering a potential policy change to allow full water bottles through security checkpoints, though no deadline has been provided for this decision [1][alert! ‘No deadline provided for policy change’]. TSA officers remain available to assist travelers with larger items or special needs to help ensure a smooth screening process [1][2].
