Bring an Empty Water Bottle Through Security

The Problem

You buy a $5 water bottle at the airport every flight. That's $50-100/year if you fly regularly.

The Hack

Bring an empty reusable water bottle through security (empty passes TSA rules). Fill at any water fountain or bottle-filling station past security.

Why It Works

TSA prohibits liquids over 3.4 oz, not empty containers. Every airport has water fountains and bottle-filling stations past security. Free, unlimited water for every flight.

Pro Tips

• Most airports have bottle-filling stations near gates
• Collapsible bottles save even more space
• Fill up before boarding — airplane water is limited
• Staying hydrated reduces jet lag symptoms
