Do you find the new TSA airport security screening procedures helpful for your travel experience?
The Transportation Security Administration has launched new 3D X-ray security scanners at airports across the United States. These machines use advanced imaging technology that allows passengers to keep laptops inside their carry-on bags.
Why it matters
The upgraded scanner design is required to accommodate high-resolution imaging technology that improves security screening performance. While the new hardware is more powerful, the change in dimensions necessitates new loading procedures for travelers.
The new CT scanners feature an opening 1 inch smaller than older versions, though standard carry-on bags measuring 22'' x 14'' x 9'' still fit inside the machines. Travelers must place all bags into bins for scanning while continuing to follow the 3-1-1 liquid rule.
The players
Transportation Security Administration
The federal agency responsible for the security of the traveling public in the United States.
The details
Passengers must now use bins to feed luggage into the scanner instead of placing items directly onto the conveyor belt. If a carry-on bag does not fit through the smaller opening, TSA officers are available to provide manual assistance with the screening process.
Timeline

Travel Outlook
This deployment marks the latest phase of the Gateside by TSA program, which focuses on integrating next-generation security hardware into high-traffic travel hubs. The program is expected to expand across the nation following the completion of current operational evaluations.
Travelers should be prepared to place their carry-on bags into bins rather than directly on the belt when using these new 3D scanners. You must still adhere to the 3-1-1 rule, which limits liquid containers to 3.4 ounces, even though laptops can remain inside your luggage.
The takeaway
While the 3D scanners offer more convenience by allowing passengers to leave laptops in their bags, the slightly smaller opening may require extra care when loading your luggage. Familiarizing yourself with these bin-loading requirements can help ensure a smoother experience through airport security.
What happens next
The Gateside by TSA program will undergo further operational evaluation before the agency determines the schedule for a wider rollout at additional airports across the country.
