Travelers may encounter construction-related changes at LAX as work progresses

Skip the hassle at LAX

Flying through Los Angeles International Airport can test anyone’s patience, especially at the security checkpoint. That experience is about to get a little easier thanks to a major federal technology upgrade.

The Transportation Security Administration is introducing advanced 3D scanners that are designed to improve security while helping travelers move through screening with fewer delays.

The new system is already arriving at LAX as part of a $781.2 million nationwide rollout. For many passengers, it means spending less time unpacking bags and more time getting to the gate. Here is what the changes could mean before your next flight.

A smarter look inside your bag

The biggest change comes from advanced computed tomography, or CT, scanners. Unlike older X-ray machines that produce flat images, these scanners create detailed 3D views of carry-on luggage. Security officers can rotate the images and inspect items from different angles without opening many bags.

That extra detail helps agents identify potential concerns more accurately. It also reduces the need for manual bag inspections in many cases. Travelers may notice that the screening process feels smoother because officers can review bag contents more efficiently.

Keep more items packed

One of the most welcome improvements is that many travelers no longer need to remove laptops, tablets, or approved liquids from their carry-on bags when using the new scanners. That means fewer bins to manage and less rushing while people wait behind you.

Keeping belongings inside your bag saves time for both passengers and security officers. It also cuts down on the chance of leaving something behind at the checkpoint, making the overall experience less stressful for busy travelers.

Shorter waits for busy flyers

Airport security lines often slow down because travelers stop to unpack electronics and other items. When fewer people need to reorganize their bags, the screening line can move at a steadier pace. That benefits everyone, especially during peak travel seasons.

Although wait times still depend on passenger volume and staffing, the updated scanners are expected to reduce some common delays. Faster screening means travelers may spend less time standing in line and more time relaxing before boarding.

Better images improve security

The new CT scanners are not just about convenience. They also give Transportation Security Administration officers clearer images of what is inside each carry-on bag. That helps them identify suspicious objects with greater confidence while reducing unnecessary searches.

More accurate screening supports both safety and efficiency. Instead of relying on limited flat images, officers can closely inspect different layers of a bag without opening it. That makes it easier to separate harmless items from those that need a closer look.

Little-known fact: TSA and LAX showcased computed tomography screening for carry-on bags at LAX’s Terminal 1 in August 2018.

One catch for large bags

There is one important detail travelers should know before heading to the airport. The opening on many of the new CT scanners is slightly smaller than that of the older screening machines. Bags that barely fit before could now create a problem.

If a carry-on cannot pass through the scanner, passengers may have to leave the security line and return to the airline counter to check the bag. Measuring your luggage before leaving home could help you avoid that inconvenience.

Carry-on rules matter more now

Many travelers have become comfortable squeezing oversized bags into airport screening systems. The newer scanners leave less room for that approach because the equipment has stricter size limits for items entering the machine.

That does not mean airline carry-on rules have changed, but enforcement could become more noticeable if a bag cannot fit through the scanner. Packing a properly sized carry-on may save valuable time and prevent last-minute surprises at the checkpoint.

Film photographers take note

Travelers who still use traditional film cameras should pay close attention to the new screening process. The stronger imaging technology used by CT scanners can damage unprocessed photographic film, even if it is stored inside a camera bag.

Photographers carrying film rolls should ask Transportation Security Administration officers for a manual inspection before placing their bags through the scanner. Taking that extra step can help protect valuable photos that cannot be replaced after exposure.

Fun fact: TSA recommends travelers request a hand inspection for undeveloped film because CT scanners can damage it.

Fewer manual bag checks

Nobody enjoys hearing their bag has been pulled aside for extra inspection. One advantage of the new CT technology is that it provides officers with a clearer view from the start, reducing the need to search many bags by hand.

That can make the checkpoint feel less crowded and help passengers move through more quickly. While some bags will still require additional screening, many travelers may notice fewer interruptions during the security process.

A nationwide investment

The upgrade at LAX is part of a much larger federal effort to modernize airport security across the country. The Transportation Security Administration is investing more than $781 million to expand advanced screening technology at major transportation hubs.

As additional airports receive the new scanners, travelers could experience a more consistent security process during domestic trips. The goal is to improve safety while making routine airport screening less frustrating for millions of passengers each year.

What travelers should do

Preparing for airport security remains important even with the new equipment. Check your airline’s carry-on size limits before packing, organize your belongings neatly, and arrive with enough time to complete screening without feeling rushed.

If you are carrying unprocessed film, remember to request a manual inspection before reaching the scanner. A little preparation can help you take full advantage of the updated technology and avoid delays that could affect your travel plans.

A smoother future for flying

Airport security is unlikely to become everyone’s favorite part of flying, but technology continues to make the experience more manageable. Better scanners can help improve safety while reducing some of the everyday frustrations travelers have faced for years.

For people flying through LAX, the new system offers a practical improvement that could make each trip feel a little easier. Packing smart, following carry-on rules, and knowing what to expect will help you get through security with less stress.
