TSA Liquids Rule 2026: Which Airports Skip the Bag-Out

The Quick Answer

The 3-1-1 rule has not changed. In 2026 you can still only bring liquids, gels, aerosols, creams and pastes through security in containers of 3.4 ounces (100 ml) or less, all packed into one quart-sized bag. TSA’s own liquids-rule page still says exactly that. Anything bigger goes in checked baggage.

What has changed is the machine, not the rule. TSA is swapping its old X-ray units for CT (computed tomography) scanners, and at a CT lane you can leave your quart bag and your laptop inside your carry-on instead of pulling them out. The containers still have to be travel-sized. You just skip the bag-out ritual.

The catch — and it’s the whole story — is that CT coverage is wildly uneven. Big hubs like Atlanta, JFK, LAX, O’Hare and Dallas/Fort Worth have CT lanes, but not in every terminal and not at every checkpoint. Fly out of a smaller airport, or even a different terminal at the same hub, and you’re back to the old rules. So pack as if the bag-out still applies, and treat any lane that lets you keep it packed as a bonus.

What the TSA Liquids Rule Actually Says in 2026

Let’s kill the myth first, because the search results are full of it. Nothing about the liquids limit itself has been repealed.

The rule, in plain terms: liquids, aerosols, gels, creams and pastes go in your carry-on only in containers of 3.4 ounces (100 ml) or less. Everything fits in a single quart-sized zip bag. Bigger bottles go in your checked bag or stay home. That’s straight from TSA’s liquids-rule page, and it reads the same in 2026 as it has for years.

It’s a nearly twenty-year-old rule. The 3-1-1 limit dates to September 2006, after British police foiled a plot to detonate liquid explosives on transatlantic flights, according to CNN. Larger quantities have always been fine in checked luggage — the restriction was only ever about what you carry into the cabin.

So if a listicle tells you the liquids rule “changed” in 2026, it’s blurring two different things: the rule, and the hardware that screens it.

What Changed Isn’t the Rule — It’s the Scanner

Here’s the actual news. TSA is replacing its flat, two-dimensional X-ray machines with CT scanners that build a rotating 3D image of your bag. The software can pick apart what’s inside — including liquid explosives — without an officer asking you to unpack.

That’s why CT lanes let you keep things in the bag. When TSA installed new CT machines at Juneau International in July 2026, its own announcement spelled it out: at CT-equipped lanes, passengers can leave laptops and other electronics in their carry-ons and don’t need to remove their travel-sized 3-1-1 liquids. “CT technology utilizes advanced algorithms to identify explosives, including liquid explosives and other threat items,” said Peter Duffy, TSA’s Alaska Federal Security Director.

This isn’t brand-new tech. TSA started testing CT at Phoenix Sky Harbor and Boston Logan back in June 2017, and JFK got a unit in July 2018, per TSA’s computed-tomography program page. What’s new is the scale of the rollout — and the fact that it’s happening one lane at a time.

That last part matters. TSA’s own CT program page still describes keeping your laptop and liquids packed as a forward-looking goal of the technology, even while its airport-specific press releases — Juneau, West Virginia’s Yeager, and others — describe that exact benefit as live today at those checkpoints. Read together, they tell you the truth: this is being switched on lane by lane, not flipped as one national policy.

Where CT Lanes Actually Are: ATL, JFK, LAX, ORD, and DFW

The rollout is moving fast. A June 2026 report counted 678 CT units across 218 airports, with $15 million committed for the fiscal year, per Travel Research Online. By early July, TSA was citing 1,162 units across 296 airports, according to a spokesperson quoted by AFAR — a big jump in a few weeks, and TSA says it’ll keep replacing the old X-ray fleet “as funding allows.”

The hubs named again and again in 2026 coverage are the obvious ones: Hartsfield-Jackson Atlanta (ATL), Chicago O’Hare (ORD), Los Angeles International (LAX), New York’s JFK, and Dallas/Fort Worth (DFW). The whole thing traces back to a pilot TSA ran with American Airlines at JFK’s Terminal 8, per IBTimes. If you fly through one of these five, there’s a real chance you’ll hit a CT lane.

“A real chance” is doing a lot of work in that sentence, though. Which brings us to the part the generic guides skip.

The Catch: Not Every Terminal in a ‘CT Airport’ Counts

This is the whole reason this article exists. Being a “CT airport” doesn’t mean the whole airport has CT.

Deployment is uneven inside the same building. As National Traveller has reported, not every checkpoint or terminal at ATL, LAX, JFK, ORD or DFW runs CT — so you can clear security with full-size liquids at one terminal and lose them at another terminal in the same airport, or on your flight home.

I fly out of JFK constantly, and this is exactly the trap. One traveler report collected by National Traveller sums it up: a flyer sailed through JFK’s Terminal 4 with full-size toiletries, no questions asked — then two weeks later, Terminal 1 at the same airport confiscated everything. The agent’s explanation was that only certain checkpoints have the exemption, and there’s no way for passengers to know which ones in advance. (Terminal 4 is Delta’s home turf; if that’s your carrier, our Delta’s JFK Terminal 4 gate guide covers the layout.)

So don’t read “JFK has CT” as “I can bring my full-size shampoo through JFK.” Read it as “some lanes at JFK might let me keep my quart bag packed.” Different sentence entirely.

Flying Through a Smaller or Regional Airport? Assume the Old Rules

CT coverage skews toward big hubs, and it’s expanding checkpoint by checkpoint. Smaller and regional airports are far more likely to still run old X-ray lanes where everything comes out of the bag.

That’s the connection trap. You might depart a CT-equipped hub without pulling your liquids out, feel clever about it, and then get stopped on the return leg out of a smaller airport that never got the machines. The rule didn’t move. The hardware just isn’t there.

The safe move is boring, and it works: pack every trip as if no CT lane exists. Quart bag, 3.4-ounce containers, ready to pull out. Anything bigger goes in a checked bag. If you land in a CT lane that lets you keep it packed, great — you saved thirty seconds. You just never build your packing around getting lucky. And if you’re not sure how much cushion the checkpoint will eat, here’s how early you actually need to arrive.

Even in a CT Lane, Bag Size Still Matters

One more thing the excitement glosses over. CT scanners come with a physical downside: the tunnel is smaller.

A CT tunnel runs about 24.5 inches wide by 16.5 inches tall — noticeably tighter than the old X-ray units, per AFAR. An overstuffed or oversized carry-on that won’t fit gets pulled for manual screening or sent to a non-CT lane, and TSA’s own advice is to check a bag that big with your airline rather than force it through.

So the CT lane that saves you the liquids bag-out can cost you time if your roller is jammed to the seams. If you’re already right at the carry-on size limit, that convenience can quietly flip on you.

TSA PreCheck Already Does This — Everywhere

Here’s the unglamorous truth the CT hype buries: if you want to reliably keep your liquids and laptop packed, TSA PreCheck already does that, at every lane, nationwide.

PreCheck members keep shoes, belts, light jackets, laptops and 3-1-1 liquids in place regardless of the scanner in front of them, per TSA. That’s a broader and far more predictable benefit than hoping the specific checkpoint you’re standing at happens to have a CT machine. TSA is even installing CT scanners in some PreCheck lanes now at select airports, which is a nice bonus — but the packed-bag perk was baked into PreCheck long before the CT rollout, and it doesn’t depend on which terminal you drew.

If you’re weighing whether it’s worth it, we’ve compared the options in TSA PreCheck vs. CLEAR — and the rest of the checkpoint-timing question lives in our full security tag hub.

Will the 3.4-Ounce Limit Itself Ever Go Away?

Maybe. Not yet. And don’t pack around it.

In July 2025, Homeland Security Secretary Kristi Noem said she was “questioning” the liquids rule and floated that loosening it “may be the next big announcement,” days after TSA scrapped its shoes-off policy, according to Axios. That got a lot of headlines. But as of late 2026, no nationwide change to the 3.4-ounce limit has actually followed.

Keep the two stories separate. The hardware story — CT scanners letting you keep the quart bag packed — is real and happening now. The policy story — TSA someday lifting the container-size limit itself — is speculation until TSA publishes an actual rule. CT scanners change whether you unpack the bag, not how big the bottles inside it can be, and no formal rule lifting that limit nationwide has been announced.

Quick Answers

Has the TSA liquids rule changed in 2026? No. The 3-1-1 rule still stands: containers of 3.4 ounces (100 ml) or less, all in one quart-sized bag, per TSA. Larger liquids still go in checked baggage.

Which airports have CT scanners? By early July 2026, TSA reported 1,162 CT units across 296 airports, per AFAR. Major hubs including ATL, JFK, LAX, ORD and DFW are consistently named, but coverage is not airport-wide.

Do I still need a quart bag at ATL, JFK, LAX, ORD or DFW? Yes — pack one anyway. Even at those hubs, CT isn’t in every terminal or checkpoint. One traveler cleared JFK Terminal 4 with full-size liquids and then lost them at Terminal 1 weeks later, per National Traveller.

Does PreCheck make this moot? Largely, yes. PreCheck members keep liquids and laptops packed at every lane nationwide, per TSA — more reliable than betting on a CT lane. The 3.4-ounce container limit still applies to everyone.
