So, you might be wondering, what's the big deal about liquids in your carry on bag? Well, it's all about security, baby! The TSA has strict rules about what kinds of liquids, gels, and aerosols you can bring on board, and it's all about keeping the bad guys from getting their hands on anything that could be used to harm you or others.
Now, we know what you're thinking: "But what about my favorite shampoo or hair gel?" Don't worry, folks, we've got you covered! The TSA allows you to bring 3.4 ounces or less of these kinds of items in your carry on bag, as long as they fit in a clear, quart-sized zip-top bag. Easy peasy, right?
