Airport security's changing. Big time. For what feels like forever, that whole 100ml liquids thing has been the bane of every traveler's existence - you know the drill, stuffing tiny shampoo bottles into a pathetic clear bag while trying not to look suspicious. But here's the thing - fancy new CT scanners are finally making some airports ditch the rule altogether. These machines do 3D scans of your bag, so security can see everything from every angle without making you unpack. Suddenly you can bring bigger liquids - like up to 2 liters - straight through. Wild, right? So where can you actually skip the whole liquid drama? Mostly in the UK and Europe right now. Some airports have gone all-in with these scanners and permanently killed the 100ml limit. Here's who's doing it: Okay so not everywhere's on board yet. And honestly, it's not that simple. Here's why some airports are dragging their feet: It's a total mixed bag depending where you are. In the US, the TSA has installed CT scanners at over 300 checkpoints across the country. But here's the kicker - they haven't actually lifted the 100ml rule. Even at airports with the new tech like Atlanta, Chicago O'Hare, or LAX, you still have to follow the 3-1-1 rule. Canada's the same story - strict enforcement at Toronto Pearson and Vancouver, with no plans to drop the limit anytime soon. This is where it gets confusing. Lots of airports have only upgraded some lanes. So you might walk through one lane where you can keep your liquids in your bag, and the next lane over you're still pulling everything out. Total headache. Here's what's happening: Yep. London City's completely dropped the 100ml rule. You can carry any size liquid - even a full 500ml or 1-liter water bottle - as long as it fits in your hand luggage and the CT scanner says it's safe. No more chugging your water before security. This is super important. The rule applies at the airport where you actually go through security. So if you start at London City (no rule) but connect through Frankfurt (still has the rule), you'll have to follow the 100ml limit when you get re-screened in Frankfurt. Always check the rules for every single airport on your trip. The UK government basically forced the issue by setting a hard deadline of June 2024 for all major UK airports to install the scanners. Plus UK airports are smaller and decisions get made faster. In the US, the TSA's taking a slower, more careful approach. And honestly, with so many massive airports across the country, rolling this out nationwide is gonna take forever and cost a fortune. Nope. That's one of the best parts of the new scanners - they can see through everything in 3D. At airports that have fully upgraded (like London City or Schiphol), you can leave your laptop, tablet, whatever in your bag. But if you're at an airport still using old scanners, you'll still have to pull everything out.Which airports no longer have the 100ml rule
