2. Freeze Your Liquids

Liquids aren’t allowed past security, which is a huge pain because we all get stuck buying overpriced water at the gate. A common hack is to bring an empty reusable water bottle, but did you know you can actually get your plastic bottles past security? This may sound odd, but according to TSA you can bring liquids as long and they’re frozen solid. If you’re looking to save a few bucks, consider freezing your water bottle.
