Staying hydrated while traveling can be challenging due to TSA's strict 3-1-1 liquids rule. However, travelers can transport water through security by freezing it solid in reusable bottles. TSA allows frozen liquids as long as they are frozen solid when checked. It is recommended to use food-grade, BPA-free bottles filled two-thirds full to prevent cracking due to expansion when freezing. The article also suggests a selection of reusable water bottles that are ideal for this method, highlighting their convenience and cost-effectiveness for travelers.
Staying properly hydrated in the summer can already be difficult, but the Transportation Security Administration (TSA)'s strict rules surrounding liquids can make it even harder to keep your thirst quenched while traveling.
You can sneak H2O through security by just freezing it. That's right—you can bring in a full bottle of water through TSA, so long as it’s frozen solid.
Frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening, a U.S. TSA spokesperson previously shared with CNN.
You should only freeze water in food-grade, BPA-free plastic or silicone reusable water bottles, and you should aim to fill them only two-thirds of the way full.
