![]() ![]() It made it sound like the 3-1-1- liquid rule would go on for, you know, forever. Allowing passengers to carry liquids, gels and aerosols in smaller containers lessens the risk. Why can’t we bring more than 3-1-1 liquids through those scanners/airports yet, if the technology is there and functional? Hello! I’ve read that TSA currently has over 500 CT scanners deployed at 180 airports in the U.S. However, DMs (Direct Messages) tend to work best for me. Plenty of people just put their questions out there in a public tweet. Of course, you’re always welcome to go directly to Twitter and ask them there, too – TSA representatives are available to answer questions from 8am to 6pm ET. The app has a link to AskTSA’s Twitter presence. The app honestly wasn’t worth much for a while, but it got a major update in 2019 that made it genuinely useful. ![]() The MyTSA app has been around since 2011. So I did what any other citizen would do…I asked the TSA. has the new scanners? Or a certain percentage of them? Or until it’s available all around the world? Or…when? But it did get me wondering…if more and more checkpoints are getting CT scanners, why hasn’t the 3-1-1 rule changed for those airports that have them? Are we going to have to wait until every single airport in the U.S. This equipment is similar to what is used to scan checked baggage for explosive devices, and has been “sized” to fit at checkpoints to create such a clear image of a bag’s contents that the system can automatically detect explosives, including liquids, by shooting hundreds of images with an X-ray camera spinning around the conveyor belt to provide TSA officers with the three-dimensional views of the contents of a carry-on bag. Here’s what the TSA said in a press release when Harrisburg International Airport got one of these state-of-the-art CT scanners (boldtype is mine, for emphasis): But we’re a big country, and it’s a start. Unfortunately, that’s just 3.6% of our commercial airports. As of September 2022, there were more than 500 CT scanners deployed at 180 airports in the United States. The TSA has also invested in CT technology over the past few years and is slowly installing the new scanners at our 5,000 public-use airports. So where does that leave us here in the good ol’ U.S. ![]() In July, 2022, another airport announced the use of CT scanners, meaning the end of passengers carrying small bottles of liquids in their carry-on.Īmsterdam Schiphol has actually been using the technology for even longer – since 2020 – but the airport advises that passengers still use 100-milliliter containers, to avoid problems when flying to other jurisdictions. Liquids (and electronics) at that airport can now remain in carry-on bags at the security checkpoint, and there are no restrictions on liquid volume. In fact, in March, 2022, the first airport in the world ended its version of the 3-1-1 rule. Thanks to the improvement of computed tomography (CT) technology, airport security agents with CT scanners can have a much clearer view of what’s in your carry-on bag. The thing is, since that post was written, technology around the world has improved dramatically. Regardless, it’s been well over a decade since it was originally written, and 3-1-1 continues. Meanwhile, fast forward to today, and Hawley’s blog post is gone. At the time, Elliott said, “The 3-1-1 rule isn’t scheduled to be lifted until the end of this year, when X-Ray machines at security checkpoints will have upgraded software proven to detect threat liquids in any configuration.” By May 2010, Christopher Elliott said on NBC News that it still hadn’t happened. In 2008, Hawley, on the agency’s blog, in a piece called “path forward on liquids,” suggested that 3-1-1 restrictions could be loosened as early as sometime in 2009, and they would remove the size limits on liquids in carry-ons. Unfortunately, it was part of the “legacy/obituary” for the guy who had been the TSA Administrator at the time, Kip Hawley. (By the way, this quick explanation of how the TSA managed to start the liquid ban, OVERNIGHT, is pretty fascinating. It’s been like that at just about every commercial airport around the world, ever since. Initially, we weren’t allowed to carry ANY liquids or gels in our carry-on bags but that was eventually revised to allow small amounts under 100mls/3.4 ounces. ![]() At that time, British authorities reportedly stopped a plot to blow up planes headed for the United States with liquid explosives. They are limited to 3.4 ounces (100 milliliters) or less per item (well, with these 10+ exceptions ) In the United States, the TSA says y ou’re only been allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes through the checkpoint. The air travel world has been living with the “3-1-1 liquids rule” (or its country-specific equivalent) for a long time now. ![]()
