The New Era of CT Scanners
Remember the frantic scramble to pull laptops, tablets, and liquids out of your carry-on? That routine is slowly becoming a thing of the past at many U.S. airports. The TSA has been rolling out Computed Tomography (CT) scanners, which create a 3D image
of your bag’s contents, allowing security officers to get a much clearer look without you having to unpack everything. What does this mean for you? If you’re at a security lane with one of these new machines, you’ll likely be instructed to leave approved electronics and 3-1-1 liquids inside your bag. This significantly speeds up the line for everyone. However, the rollout isn't universal. Don't assume you can leave items in your bag; always listen to the specific instructions from TSA officers at the checkpoint, as you might be in a lane with older X-ray equipment. The bottom line: be prepared to unpack, but be pleasantly surprised if you don’t have to.
Your Digital ID Is Going Mainstream
Your phone is your wallet, your map, and your boarding pass—and now, it can be your ID. The TSA is expanding its use of Credential Authentication Technology (CAT) units that can accept mobile or digital driver’s licenses from participating states. Travelers with a digital ID stored in their Apple Wallet or Google Wallet can simply tap their phone on the scanner instead of handing over a physical card. As of now, this technology is available at dozens of airports and for residents of states like Arizona, Colorado, Maryland, and Georgia, with more joining regularly. The process is designed to be more secure and touchless. The officer never has to handle your phone, and the system verifies your identity and flight status in one step. Before relying on it, check the TSA website to confirm your departure airport and state's digital ID are part of the program.
The REAL ID Deadline Looms (Again)
The long-delayed enforcement of the REAL ID Act is officially back on the calendar. Starting May 7, 2025, every traveler aged 18 and older will need a REAL ID-compliant driver’s license, state-issued enhanced driver’s license, or another acceptable form of ID (like a passport) to fly within the United States. A standard, non-compliant license will no longer be accepted at TSA checkpoints. How do you know if your ID is compliant? Most REAL IDs have a star marking in the upper corner (this can vary by state, so check with your local DMV). While the deadline has been pushed back multiple times, there is no indication it will be delayed again. Waiting until the last minute could mean facing long lines at the DMV. Check your license now. If it’s not compliant, make a plan to update it well before the 2025 deadline to avoid any travel disruptions.
Larger Powders Require Extra Screening
The liquids rule (3.4 ounces or 100 milliliters) is etched into every traveler's brain, but a lesser-known rule for powders can also cause delays. Since 2018, powder-like substances in containers larger than 12 ounces (350 ml)—about the size of a standard soda can—are subject to secondary screening. This includes items like protein powder, baby formula, spices, and certain cosmetics. Unlike liquids, these larger powders are not banned from carry-on bags. However, you will need to remove them for a separate screening, which adds a step to your security process. TSA officers may need to open the container to inspect the contents. To keep things moving, the TSA recommends placing any large powders in your checked luggage. If you must carry them on, take them out of your bag and place them in a separate bin to declare them upfront.
International Entry Gets a Biometric Boost
If you’re returning to the U.S. from an international trip, you may notice a streamlined customs process. U.S. Customs and Border Protection (CBP) is increasingly using biometric facial comparison technology. Instead of handing your passport to an officer, you may simply pause for a photo, which the system matches against the photo in your passport or visa. This technology is intended to be faster and more secure, reducing the reliance on physical documents. It’s also the backbone of programs like Global Entry, which allows pre-approved, low-risk travelers to skip long processing lines. Furthermore, the Mobile Passport Control (MPC) app allows eligible travelers to submit their passport and customs declaration information via their smartphone, often granting access to a shorter, dedicated line. Downloading and setting up the MPC app before you land can be a game-changer after a long international flight.
