According to the 3-1-1 rule, a passenger can carry no more than 3.4 ounces per container of liquid. It must fit into a clear, one-quart bag, and only one bag is allowed per passenger. Always remember: 3-1-1: 3.4 ounces or smaller-1 quart bag-1 bag per person.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_the_3-1-1_Rule_Limited_to_Liquids\"><\/span><strong>Is the 3-1-1 Rule Limited to Liquids?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The TSA liquid rule applies not just to liquids but also to gels, creams, foams, aerosols, and pastes. It limits the passengers from carrying anything that can be spilled, sprayed, poured, or pumped in the carry-ons.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Does_TSA_Have_a_Liquid_Rule\"><\/span><strong>Why Does TSA Have a Liquid Rule?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The liquid rule was an immediate reaction by the Department of Homeland Security (DHS) following a foiled 2006 transatlantic terror plot. The apprehended attackers were planning to smuggle liquid explosive onto planes flying from London to the United States. These explosives were disguised as regular drinks in drink bottles. Soon after the incident, the 3-1-1 rule was implemented, bringing strict regulations on the liquids passengers can carry on flights.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Does_the_TSA_Liquid_Rule_have_an_Exception_List\"><\/span><strong>Does the TSA Liquid Rule have an Exception List?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Yes, it does. Indeed, the TSA liquid rule was initially created to keep liquid explosives away from planes. But today, fortunately, with the advancement of technology and the introduction of enhanced CT scanners, threat detection has become effortless. Hence, there are exceptions to the TSA liquid rule. Here are a few types of liquids allowed now through the TSA check as per the 2025 list:<\/p>\n<p><strong>Prescription Medication<\/strong>: You can bring any liquid, aerosol, or gel prescription medications, as long as they are in their original, labeled containers. You should also declare it to the officers at security and remove it for separate screening.<\/p>\n<p><strong>Over-the-Counter Medicines:<\/strong> As per the new list, you can bring almost all over-the-counter medicines in your carry-on, as these are not subject to the usual travel restrictions of prescription medicines. This includes allergy medication, pain relievers, etc.<\/p>\n<p><strong>Ice Packs &amp; Gel Packs<\/strong>: TSA allows you to carry ice packs or gel packs in your carry-on luggage. If you\u2019re carrying temperature-sensitive medication that should be kept cold.<\/p>\n<p><strong>Breast Milk\/Formula<\/strong>: You can carry baby formula and breast milk in amounts more than the standard 3.4 ounces. Once declared and screened separately, you&#8217;ll be good to carry them on board. You do not need to travel with your child to bring breast milk either.<\/p>\n<p><strong>Baby Food<\/strong>: TSA generally allows you to carry baby food in your carry-on without restrictions.<\/p>\n<h4><strong>Other Curious Exemptions<\/strong><\/h4>\n<p><strong>Live Fish Transport<\/strong>: You can transport live fish in carry-on luggage, but make sure they are in a clear, sealed, spill-proof container and subject to TSA visual inspection, requiring you to declare them at the checkpoint for separate screening.<\/p>\n<p><strong>Biological Samples<\/strong>: If the biological samples are stored properly, then they are free from the TSA liquid rule. Also, check the TSA website or contact them directly for specific guidance on your sample type to ensure smooth screening and compliance.<\/p>\n<p><strong>Duty-Free Purchases<\/strong>: The 3-1-1 rule excuses duty-free products like liquor or perfumes purchased after security. Although they have to be in their original, sealed packaging. You should also carry its receipt.<\/p>\n<h3><strong>Are there any tips for following the TSA Liquid Rules?<\/strong><\/h3>\n<p>Yes, there are many tips one can follow to embrace the TSA liquid rules:<\/p>\n<p><strong>Go for the Miniatures\/Decants<\/strong>: Rather than stuffing the full-sized bottles in your luggage, it\u2019s better to carry miniatures\/decants of your toiletries in your carry-on. Not only will everything fit into a quart-sized bag, but they will also be readily available for your convenience.<\/p>\n<p><strong>Solid Alternatives for the Eco-conscious<\/strong>: If using miniatures is not up your alley, then you can try solid alternatives &#8211; toothpaste powders, shampoo bars, and solid perfumes. Without plastic packaging, it\u2019s also environmentally friendly.<\/p>\n<p><strong>Buy at Destination<\/strong>: A third alternative could be to just get your toiletries after you\u2019ve reached your destination. This way, you can save space in your carry-on while also breezing through the TSA checks.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The TSA liquid rule was introduced by the Transportation Security Administration (TSA) to increase airline safety.
