Can I Fly With This?

CT scanners at US airports

The TSA's CT-scanner rollout is uneven. At full-coverage airports you can keep liquids and laptops in your bag. At partial-coverage airports, only PreCheck lanes have them. Here's the status for 116 US airports across all 50 states, DC and 4 territories (PR, USVI, Guam, CNMI), as of May 2026.

The 3-1-1 rule is still official TSA policy at every US airport (unlike the UK, where Heathrow T5 etc. officially scrapped 100 ml at CT lanes). What CT scanners change in the US is enforcement: at CT lanes, agents typically wave through liquids over 100 ml and full water bottles, and laptops/tablets stay in the bag. At standard X-ray lanes (often staffed in parallel) the old rules still apply.

Pair this with the 100 ml bag fitter if you're flying out of a standard-X-ray airport. For an item-by-item check (water bottle, perfume, baby formula), use the liquids rules page. For airline-specific carry-on size limits, see the bag size checker. PreCheck lanes get CT-scanner access first at most airports — see whether PreCheck / Global Entry / Clear makes sense for how you travel.

Methodology + Sources

Coverage classifications (full / partial / select) are based on publicly reported TSA deployment milestones, airport authority press releases, and aggregated traveler reports. The TSA does not publish a per-airport-per-lane CT-scanner inventory; status here reflects the best public snapshot as of May 2026.

⚠️ CT-scanner deployment changes monthly. This page reflects publicly reported TSA rollout status as of May 2026 based on TSA press releases and airport authority announcements. Even at "full coverage" airports, individual checkpoint operations may swap to standard X-ray during equipment maintenance. Always pack as if 3-1-1 applies — that way you're never caught out.
