TSA CT Scanner Rollout Sends More Carry-Ons to Checked Baggage
The TSA's nationwide deployment of CT scanners is forcing more rolling carry-on bags to be checked due to narrower tunnel openings, despite the same airline size limits.

The Transportation Security Administration's rollout of computed tomography scanners at airport checkpoints is having an unexpected side effect. More rolling carry-on bags are being rejected and sent back to be checked.
The new CT scanners let passengers leave laptops and travel-size liquids inside their bags during screening, but the tunnel opening is narrower than on the older X-ray machines they are replacing. Many standard-size rolling carry-ons that previously fit through the X-ray tunnel now do not fit through the CT scanner.
The airline's size limit for carry-on bags has not changed. The machine is the limiting factor. The TSA has spent $781.2 million retrofitting checkpoints at hundreds of airports with these new scanners.
