From Checkpoint Scanners to Gate Checks: How Flying with Essential Travel Gear Evolved
By Chloe Bennett
The era of kicking off footwear onto linoleum floors is nearing a technological turning point. Airport checkpoint scanners equipped with computed tomography (CT) generate high-resolution, three-dimensional volumetric images of carry-on items. Algorithms cross-reference the atomic density of objects against explosive signatures, allowing liquids and laptops to remain securely packed.
In lanes where advanced CT units are integrated alongside high-throughput millimeter-wave body scanners, the operational justification for universal shoe removal begins to erode. Low-cut footwear with minimal sole density can be verified without physical removal, provided the passenger clears walk-through imaging. Trusted traveler programs like TSA PreCheck already exempt enrolled passengers from removing shoes, light jackets, and belts.
Widespread adoption, however, remains uneven. A single commercial CT scanner installation costs between $300,000 and $600,000, requiring reinforced checkpoint flooring due to machine weight exceeding 5,000 pounds. While primary tier-one hubs in London, Amsterdam, and Atlanta have updated their terminal flows, secondary regional airports still rely on legacy dual-energy transmission x-rays. For millions of passengers, taking off footwear remains a standard checkpoint reality.
