Bring a Reusable Water Bottle

Most travelers don’t realize that while you can’t bring liquids through airport security, you can bring an empty reusable water bottle—and it can save you money and reduce waste throughout your trip. Once you pass through security, simply refill it at a water fountain or café. Many airports now have dedicated refill stations with filtered water.

This is especially useful on long travel days, in destinations where bottled water is expensive, or when flying with kids who get thirsty often. Plus, it’s an eco-friendly habit that makes a difference.
