Travel Hydration Tactics
You Should Absolutely Bring a Reusable Bottle—But Know the Rules
Reusable bottles are permitted through airport security, as long as they’re completely empty. It’s one of the simplest ways to dodge airport markups and stay hydrated, but only if you avoid rookie mistakes during TSA screening. Here’s how to make it effortless, not stressful.
How to Breeze Through Security with a Reusable Water Bottle
Use this 5-step checklist to avoid hold-ups and benefit from having your own bottle on trips.
Empty Your Bottle Completely
Dump all liquid before reaching the security line.
Even a splash or melting ice can get your bag pulled aside. Don’t forget to check for any hidden sips.
Remove the Cap at Screening
Take the bottle out of your bag and open it for visibility.
Security staff can see it’s empty at a glance—reducing your odds of secondary inspection.
Place Bottle in a Bin
Lay it in the plastic tray, separate from your main bag.
Prevents accidental leaks in luggage and speeds up visual inspection.
Refill After Security
Look for dedicated water stations or use restroom sinks if needed.
Fill up before boarding. Some airports have filtered-water stations; check signage near restrooms.
Keep the Lid Tight Before Boarding
Avoid post-security leaks in your carry-on.
Snap or screw the lid firmly. Consider hard-sided bottles for better protection during turbulence or overhead bin movement.
