What happened
TSA had installed 1,162 CT units at 296 U.S. airports by July 6, 2026. The equipment can create a practical screening constraint for maximum-size carry-ons permitted by Frontier and Southwest.
Why it matters: Passengers may face rerouting, manual screening or baggage fees even when their bag complies with airline limits, particularly if soft-sided luggage bulges when packed.
