Goodbye 100 ml Rule: The United States is on the verge of one of the most significant changes to airport security procedures in over a decade. The much-hated 100 ml liquid rule, a restriction that has been in place since 2006, could soon become a thing of the past. This rule, which limits travelers to carrying liquids in containers of 3.4 ounces (100 milliliters) or less, inside a quart-sized plastic bag, has been one of the most cumbersome and widely criticized aspects of air travel. But now, with advancements in security technology, the U.S. Department of Homeland Security (DHS) is exploring the possibility of relaxing these restrictions. This change, which has been teased by DHS Secretary Kristi Noem, could revolutionize the way we travel by air. But what does this mean for passengers, airports, and the future of air travel security? In this article, we’ll break down the key aspects of this historic change, how it will impact you as a traveler, and what steps airports are taking to modernize security protocols. Let’s dive in!
Goodbye 100 ml Rule
The end of the 100 ml liquid rule is fast approaching, and this change is likely to make air travel much smoother for passengers. Thanks to advancements in screening technology, TSA will be able to maintain the high level of security we expect, while making the experience less stressful for everyone involved. It may take a few years for this change to reach every airport, but the future of air travel looks brighter and more efficient than ever.

The 100 ml Rule: A Thing of the Past?
Since 2006, the 100 ml liquid rule has been one of the most universally recognized aspects of air travel security. The rule was introduced in the wake of a foiled terrorist plot in the UK, where explosives were intended to be smuggled onto planes inside liquid containers. As a result, passengers were suddenly forced to deal with the hassle of restricted liquids, a requirement that has caused countless headaches at security checkpoints across the world.
For many of us, it’s become second nature to stuff our liquids and gels into a small plastic bag before heading to the airport, but for travelers who want to carry larger amounts of liquid (think bottled water, sunscreen, or even beverages for kids), the rule has been a major inconvenience. Now, it seems that this rule could finally be relaxed.
How Will the Change Affect You?
The change being discussed by DHS centers around the possibility of allowing passengers to carry larger containers of liquids through security checks. In particular, the implementation of advanced security screening technology could make it easier for TSA agents to detect potential threats in liquids without needing to impose strict size restrictions. For travelers, this could mean less time spent at security checkpoints and fewer restrictions on what they can bring on board.
But it’s not just about making things easier for passengers. It’s also about enhancing security. The goal is to maintain the same level of safety that the 100 ml rule provided, but to do so more efficiently, without the need for overly restrictive rules.

Advancements in Technology: A Game-Changer for Air Travel
One of the main drivers behind this potential change is the rapid advancement in airport security technology. Computed Tomography (CT) scanners, which are already being deployed in some airports, provide 3D imaging of carry-on items, giving TSA agents a much more detailed look at what’s inside bags. This technology has already shown great promise in detecting threats that might otherwise have been missed by older screening systems.
With the increased capability of these machines, it’s possible to allow larger liquid containers to pass through security without compromising safety. These CT scanners can essentially “see” inside liquids, powders, and gels, giving agents the ability to detect anything harmful, even if it’s hidden inside a large bottle. This means that soon, we might be able to breeze through security without worrying about exactly how many ounces are in our shampoo bottles.
What Does This Mean for the Future?
If successful, the new approach could dramatically change the experience of flying, making it faster and more convenient for passengers. Imagine not having to squeeze your toothpaste into tiny tubes or worrying about your kids’ juice boxes when going through security. Instead, passengers will simply walk through the checkpoint, and security systems will automatically flag any suspicious items.
However, it’s important to note that full implementation of these advanced scanners across all U.S. airports will take time. As of now, many airports still don’t have the necessary equipment to support a relaxation of the liquid rule, and experts predict it could take several years before the technology is available nationwide.

The Pros and Cons of Relaxing the Liquid Rule
Pros:
- Faster Security: With fewer restrictions, you’ll be able to get through security quicker, leading to less stress and better overall passenger experience.
- More Freedom: You’ll be able to carry larger bottles of liquids without worrying about measurements or size restrictions.
- Improved Technology: The use of advanced scanners will help catch threats more effectively and accurately.
Cons:
- Incomplete Rollout: As noted earlier, not all airports are immediately equipped with the new screening technology, so the change may be slow and uneven.
- Cost of New Technology: Implementing new technology in every airport across the country requires a substantial financial investment, which could lead to delays in the rollout.
- False Sense of Security?: There may be concerns about over-relying on technology and its ability to detect threats, even though it is very advanced.
How Airport Security is Saying Goodbye 100 ml Rule?
Beyond the changes to liquid restrictions, airport security is undergoing several other transformations to improve efficiency and safety. As travel volumes rise and security threats evolve, the TSA and DHS are continuously exploring new ways to ensure safer, faster, and more convenient air travel.
Biometric Screening
One of the most exciting advancements is the expansion of biometric screening. More and more airports are incorporating facial recognition and fingerprint scanning into their security procedures. This technology allows passengers to go through security and boarding processes without having to present tickets or identification. Instead, their biometric data, such as a facial scan, will confirm their identity. This could significantly speed up the process of getting through security while also reducing human error.
Smart Security Lanes
Smart lanes are another recent innovation. These high-tech lanes use artificial intelligence (AI) to streamline the screening process. For instance, the system automatically adjusts the speed of the conveyor belt based on the number of passengers and the contents of their bags. It even uses AI to determine whether a bag has been placed incorrectly, reducing human intervention and the need for secondary screening.
These innovations not only promise to speed up security checks but also make the whole process smoother and less stressful for passengers.
Explosives Detection Systems
As threats evolve, so too does the technology designed to detect them. Explosives detection systems (EDS) are becoming more advanced, with trace detection capabilities that can analyze even the smallest residue of harmful substances. As a result, passengers can be assured that while the security process may feel less intrusive, it is no less rigorous. The goal is to keep the skies safe while ensuring an experience that isn’t bogged down by long lines or excessive checks.

What to Expect in the Coming Years?
The government has not provided an exact timeline for when these changes will go into effect, but DHS Secretary Kristi Noem recently hinted that an announcement could be made soon. At a recent conference, she said, “I’m questioning liquids. So that may be the next big announcement—what size your liquids need to be.” This suggests that the conversation is already underway, and we could see major changes in the next few years. However, full implementation of this new policy will likely take time, as airports across the country need to install the necessary technology.
What Can You Do as a Traveler?
For now, it’s important to stick to the current rules when traveling. Ensure you’re aware of the 3-1-1 rule and prepare your liquids accordingly to avoid delays at the security checkpoint. However, keep an eye on the latest news from the DHS and TSA, as they will likely announce updates on when the change will take effect.
