What’s Changing – And What’s Not

While advanced 3D scanning technology is beginning to make its way into airports around the world, allowing for more thorough screening of carry-on items, the rollout has been inconsistent. A handful of airports have begun relaxing restrictions, permitting full-size liquid containers in carry-on luggage. However, this is far from the norm and largely limited to specific international hubs.

For U.S. travelers, the Transportation Security Administration (TSA) has not announced a nationwide plan to eliminate the 3-1-1 rule. Even as these technologies become more widespread, the transition to new liquid policies will vary by airport. This means you could encounter different rules at your departure and return airports—even on the same trip.

Why the 3-1-1 Rule Matters

The 3-1-1 rule was introduced in 2006 following security concerns over liquid explosives. It has become a standardized method of ensuring safety while allowing passengers to bring essential liquids onboard. While some advancements in scanning technology might make this rule less necessary in the future, until these systems are universally adopted, sticking to the current policy is the safest bet to avoid surprises at the security checkpoint.

Tips for Navigating Evolving Liquid Rules

1. Stick to the 3-1-1 Rule
   Until changes are rolled out nationwide, it’s best to keep packing your liquids in 3.4-ounce containers within a quart-sized bag. This ensures you won’t run into issues at security checkpoints.
2. Check Departure and Return Airport Policies
   Rules at your departure airport may differ from those at your return airport. For instance, an international airport might allow larger liquid containers due to upgraded scanners, while a smaller domestic airport might still adhere to the 3-1-1 rule. Checking each airport’s policies in advance can save you hassle.
3. Plan for the Unexpected
   Even if changes are implemented at your airport, they may not be well-communicated or consistently enforced during the transition period. Packing according to the current rules ensures you’ll be prepared regardless of the policies in place. This is esoecially true for those of us with vision issues. You can bet the signs will not be accessible in any way. 
4. Keep Liquids in Checked Bags When Possible
   If you’re worried about encountering different rules at various airports, consider packing your full-size liquids in your checked luggage. This eliminates the need to navigate changing carry-on policies entirely.

Staying the Course

While it’s exciting to imagine a future where full-size liquid containers are universally allowed in carry-on bags, it’s clear that such changes will take time to standardize. For now, staying the course with the 3-1-1 rule is the best approach. By continuing to pack as you do now, you’ll minimize disruptions and make your journey smoother—regardless of where you’re flying from or to.

We know that someday we won’t have to buy that bottle of water right after we get through TSA, but for now we do what we have to do so everyone stays safe.
