TSA 2026 Rules Explained: The $45 REAL ID Fee, Liquid Rule Myths & What Actually Changed

A claim keeps circulating online that TSA scrapped the liquid rule in 2026. It didn't — the 100 ml limit is unchanged nationwide, at every airport, regardless of scanner technology. What actually changed is more specific, and a fair amount of what's published about both topics online doesn't match what TSA's own site says.

The 3-1-1 Rule Hasn't Moved — Anywhere

TSA's official guidance is unchanged: liquids, gels, aerosols, creams, and pastes go in containers of 3.4 ounces (100 ml) or less, all fitting inside one clear, quart-sized bag, one bag per traveler. That's been the rule since 2006, and it remains the rule at every U.S. checkpoint in 2026, with or without a CT scanner in the lane. This is not a case of some airports having a different limit than others — the 100 ml ceiling is uniform nationwide.

What's changed is the equipment behind the belt, not the limit in front of it. Since 2023, TSA has been rolling out computed tomography scanners that produce a rotatable 3D image of a bag's contents instead of a flat 2D X-ray. By 2026, a large share of major-hub checkpoints have at least one CT lane. The practical benefit at those specific lanes: you often don't have to pull your liquids bag or laptop out of your carry-on. The scanner sees through the bag well enough on its own.

That's the extent of the change. The container still has to be 3.4 oz or smaller. The bag still has to be quart-sized. You'll find articles claiming CT scanners unlocked a list of exempted items beyond that — that specific claim doesn't appear on tsa.gov, which still describes the same three standing exceptions that predate the scanner rollout: medically necessary liquids (declared to an officer), baby formula and breast milk in reasonable quantities, and sealed duty-free purchases with proof of purchase. 2026 saw a wave of these unverified claims spread on social media and travel blogs; if a site tells you the limit changed, check TSA's "What Can I Bring?" tool directly before you pack around it.

The Real 2026 Change Isn't About Liquids at All

REAL ID enforcement, in place since May 2025, finally has teeth. Starting February 1, 2026, travelers 18 or older who arrive at a checkpoint without an acceptable form of ID may need to use TSA ConfirmID, an alternative identity-verification process, for a $45 fee. The important detail: REAL ID is not the only document that satisfies this requirement. TSA's accepted list also includes a valid U.S. passport or passport card, DHS Trusted Traveler cards (Global Entry, NEXUS, SENTRI), U.S. military ID, a permanent resident card, and several other government-issued documents. The fee only applies to travelers who show up with none of these — not to everyone who happens to be flying with a standard, non-compliant driver's license and nothing else.

The fee itself buys an alternative verification process, not a guarantee of getting through security; TSA states clearly that it can't promise ConfirmID will succeed. The detail that catches people off guard: the $45 payment is only valid for a 10-day travel window. A traveler who flies out, stays two weeks, and flies back without a compliant ID pays it twice — $90 for one trip. According to a CNBC report on the rollout, TSA projected roughly 10.6 million ConfirmID uses over five years and expects to collect close to $476 million in fees, calculated to cover the program's own administrative cost.

The upside: compliance is already high. TSA reported in early 2026 that 94 to 99% of travelers were arriving with a REAL ID or another acceptable form of ID, so most people never see this fee. The travelers who get hit tend to be infrequent flyers who haven't updated an old license and don't carry a passport domestically, or people who assumed a standard state license would keep working past the deadline. If there's any doubt, a state DMV can confirm REAL ID compliance in a few minutes online — cheaper than finding out at the checkpoint.

Shoes Stay On — Mostly

Since July 2025, TSA has not required most travelers to remove their shoes at security, ending a policy that had been in place since 2006. It's a smaller change than the liquid rule or the ID fee, but it's one more thing travelers still ask about at the belt, unsure if it's real. Officers retain the discretion to request shoe removal for individual travelers flagged for additional screening, and reporting in April 2026 noted a Homeland Security review questioning whether TSA's imaging scanners can fully screen shoes without removal — enough uncertainty that it's worth following officer instructions at your specific checkpoint rather than assuming the policy is locked in for good.

What Actually Trips People Up at the Belt

Two habits solve most of this before it becomes a problem.

First: pack liquids as if every airport still runs the standard rule, even if your departure airport has CT lanes — because the limit is the same everywhere anyway. Connecting through a smaller regional airport without the new scanners changes nothing about what's allowed, only how the bag gets screened. TSA measures container size, not how much product is left — a nearly empty 6 oz bottle still gets pulled for being a 6 oz container.

Second: if your ID situation is even slightly uncertain, resolve it before you leave for the airport, not in the security line. Check whether your passport, Global Entry card, or military ID is current — any of those work without needing a REAL ID at all. If none of those apply and your license isn't REAL ID-compliant, TSA's ConfirmID portal lets you pay the $45 fee online in advance, which avoids the added delay of paying on-site — and delays on this specific process have been running long enough that TSA itself warns they can cost a missed flight.

One item worth a second thought while packing: spare batteries and power banks. These stay in carry-on luggage, not checked bags, under longstanding lithium-battery restrictions that CT scanners haven't touched. A dedicated power bank like the Anker PowerCore 26800 is worth keeping in an outer pocket where it's easy to show an officer if asked — it's the kind of item that causes a bag to get pulled for a hand-check when it's buried at the bottom.

Quick Answers

Does the 3.4 oz liquid limit still apply if my airport has a CT scanner?
Yes, and it applies at every U.S. airport regardless of scanner technology. CT scanners change what you have to pull out of your bag, not the size limit on the liquid itself.

Do I have to pay $45 every time I fly without a REAL ID?
Only if you also don't have another acceptable form of ID — a passport, Global Entry card, military ID, and several other documents all work instead. If you do need ConfirmID, the fee covers a 10-day window; a longer trip that crosses that mark means paying again on the return leg.

Is my regular driver's license still valid for flying?
Only if it's REAL ID-compliant, which most states mark with a star. If it isn't, a passport, Global Entry card, or military ID all work instead of paying the ConfirmID fee. When in doubt, a state DMV site confirms REAL ID status directly.

Bottom Line

Nothing about the liquid rule has changed anywhere in the country; what's changed is how strictly TSA now enforces the ID rule that's been on the books for two decades — and even that only affects travelers with no acceptable ID at all, not everyone without a REAL ID specifically. The travelers who get caught out in 2026 aren't the ones with a slightly-too-large shampoo bottle — they're the ones who assumed an old license would still work, had no passport or Trusted Traveler card as a backup, and found out otherwise at the checkpoint, fee in hand.
