It’s time to plan ahead. And we know how.
TSA Rule Change Came out of Nowhere
A new generation of airport security scanners is making its way through the United States, promising a simpler checkpoint experience for millions of travelers. But for families flying to or from Walt Disney World, that convenience may come with an unwelcome luggage complication.
The Transportation Security Administration is installing computed tomography, or CT, scanners that allow officers to examine three-dimensional images of carry-on contents. The technology can reduce how much passengers must unpack at security—but the scanner’s entry tunnel may not accommodate every large, bulky, or overstuffed carry-on.
TSA is currently recommending that travelers check larger bags that cannot fit inside the equipment.
That distinction matters. TSA has not announced a new universal carry-on-size limit. Instead, the physical scanner itself may determine whether certain luggage can proceed through a particular checkpoint lane.
TSA’s New Scanners Change What Happens at Security
According to the Transportation Security Administration’s explanation of CT screening, the equipment creates a three-dimensional image that officers can rotate and examine from multiple angles.
At checkpoints using the technology, passengers can generally leave laptops, electronics, and permitted travel-size liquids inside their carry-ons. Every item must be placed inside a screening bin rather than directly on the conveyor belt, and TSA officers may still ask travelers to remove something when additional screening is necessary.
For Disney World visitors, especially families traveling with children, that could remove one of the most chaotic parts of airport security: unpacking electronics and liquid bags while managing strollers, shoes, identification, and several pieces of luggage.
The benefit is real.
So is the limitation.
The entrance on some CT scanners is smaller than travelers may expect. A large carry-on, irregularly shaped item, or bag expanded beyond its normal dimensions may not fit, even when its owner reached the security checkpoint believing it could travel in the cabin.
A TSA spokesperson said the equipment’s design is necessary to contain the advanced technology and added, “TSA officers are available to assist travelers with larger items or special needs to help ensure a smooth screening process.”
What that assistance will involve in every situation remains unclear.
A Carry-On Can Meet Airline Rules and Still Cause Trouble
Airlines—not TSA—establish their own carry-on dimensions, baggage allowances, and checked-bag fees. The new scanners do not replace those individual carrier policies.
They do, however, add another physical checkpoint.
A suitcase might fall within an airline’s published measurements but become too wide or tall after exterior pockets are filled. Soft-sided bags can bulge. Souvenir-filled luggage that closed easily before a Disney vacation may return home packed with merchandise, clothing, popcorn buckets, and other items that distort its original shape.
Travelers already face changing baggage costs across major carriers. Several airlines serving Orlando have raised or revised checked-bag fees, meaning an unexpected trip back to the ticket counter could become more than a minor inconvenience.
It could cost money, consume valuable time, and leave a traveler trying to rearrange luggage in the middle of the airport.
That possibility is particularly relevant at Orlando International Airport, the primary aviation gateway for Walt Disney World and Universal Orlando Resort. MCO’s security operation regularly handles families carrying more than an ordinary business traveler: car seats, medical supplies, strollers, children’s bags, toys, and vacation purchases.
TSA has not said that every large item will automatically be rejected. Travelers with medical equipment, mobility-related items, or other special needs should request help from an officer rather than assume the item cannot be screened.
Nearly 300 Airports Reportedly Have the Technology
TSA has been introducing CT scanners for several years rather than activating them through one sudden nationwide policy change.
In 2022, the agency awarded $781.2 million for additional systems. A larger 2023 procurement included options for hundreds more base-size, mid-size, and full-size units. TSA has continued announcing installations at individual airports, including new equipment installed at Juneau International Airport in July 2026.
Recent reporting citing WDHN states that nearly 300 airports already have some version of the technology. However, that does not mean every checkpoint lane at each of those airports has been converted, nor does it establish that every installed scanner has identical dimensions.
The rollout joins several other airport-security changes affecting vacation travel. TSA has also expanded biometric screening through PreCheck Touchless ID at airports including Orlando, while previous disruptions involving TSA PreCheck availability created uncertainty for Disney travelers.
Together, these changes reflect an airport experience becoming more technologically advanced—but not necessarily more predictable for every passenger.
What Disney World Travelers Should Do Before Flying
Travelers do not need to abandon carry-ons because their airport may use CT scanners. They should, however, stop treating an expandable suitcase as though its advertised dimensions remain unchanged after it is packed.
Before leaving for the airport, measure the bag at its widest and tallest points after closing every compartment. Avoid attaching items that prevent it from lying flat in a screening bin. Keep medication, identification, electronics, valuables, and essential children’s supplies somewhere accessible in case the larger suitcase must be checked.
Passengers should also confirm their airline’s current bag measurements and fees before departure. Anyone flying through Orlando during a busy period should leave additional time; TSA has previously urged MCO passengers to allow sufficient time for ticketing and security.
The scanner upgrade is intended to make checkpoints safer and easier. For most passengers, it may do exactly that.
But Disney World travelers carrying a suitcase stretched to its physical limit should resolve that problem at home—not when the bag reaches a machine that cannot accommodate it.
