You may end up checking in your carry-on bags for international flights<\/a><\/span> departing from US airports. The new TSA CT scanners, which are rolling out across the US for nearly $800 million, may send overstuffed and\/or oversized carry-on bags back to airline check-in counters. Since not all carry-on items go through 3D CT scanners, passengers should either leave them behind or check in them with the airline.<\/p><\/blockquote>\n

TSA Security Screening: CT Scanners vs Old X-ray Machines<\/strong><\/h3>\n

Nearly 300 airports in the US have installed 1200 CT scanners and replaced the old X-ray machines from TSA security lanes, as of mid-2026. Daniel Velez, a TSA spokesperson in Florida, confirmed that not all carry-on bags fit through the new advanced scanners (Computed tomography), because the tunnel opening is smaller than opening of the previous machines.<\/p>\n

The rollout of TSA\u2019s new CT scanners is a significant upgrade to US airport security and aviation safety<\/strong>. Unlike traditional luggage X-ray machines, CT scanners provide fool-proof screening of items within carry-on bags. Airport security checkpoints with the new TSA scanner don\u2019t require you to unbag 3:1:1 liquids, laptops and other electronic devices. This sort of convenience was long overdue for passengers who arrive late for a flight or get stuck in a long line.<\/p>\n

The only disadvantage of 3D luggage scanners at the US airports is their smaller opening<\/strong>, 24.5 inches (width) by 16.5 inches (height). It nearly blocks the tunnel opening for bulky carry-on items, oversized cabin bags, and bags with bulging outer compartments, requiring them to be checked. Computed Tomography scanners can accommodate and screen cabin luggage with standard dimensions (22 x 15 x 9 inches) for international flights<\/strong>.<\/p>\n

International Airlines\u2019 Carry-on Luggage Dimensions<\/strong>\u00a0<\/strong><\/h3>\n

Knowing airlines\u2019 cabin baggage sizes for international passengers helps avoid last-minute hassles, given airports and airlines\u2019 growing reliance on automated bag sizer and digital scanners for carry-ons. These days, wheels and handles strictly count towards bag sizes. Gate agents are flagging cabin luggage whose wheels, pockets, and\/or handles exceed the acceptable size limits.<\/p>\n
