TSA Rules on Hydro Flasks

According to the TSA, travellers can bring a Hydro Flask in both their carry-on and checked luggage, provided it’s empty.

If filled with a liquid, it should adhere to the standard 3-1-1 rule: liquids in containers of 3.4 ounces or less, packed in a quart-sized, clear, zip-top bag.

This means you will NOT be allowed to bring your hydro flask full because it wouldn’t fit in the bag, and you would most likely have over 100ml in there.

TSA Metal Waterbottles Guidelines

Empty Bottles: You can bring a full-size metal water bottle through the security checkpoint. However, the bottle should be empty. TSA officers will typically ask you to empty the bottle’s contents if it isn’t already empty.

Screening Process: Metal water bottles will typically need to go through the X-ray machine with the rest of your carry-on items. Ensure it’s easy to access in case TSA officers need to take a closer look.

Can I Bring a Filled Hydro Flask in Carry-On Luggage?

The answer largely depends on the liquid inside. While the Hydro Flask itself poses no issues, the liquid inside must adhere to TSA’s 3-1-1 rule. If you wish to bring a drink, ensure you finish it before the security checkpoint or be ready to pour it out.

Once you’ve passed through security, you can always buy water and hot drinks to fill up your hydroflask. However, on a plane you must only eat and drink things bought on the plane apart from things like water.

Also, remember that some airports (e.g. Colombo, Sri Lanka) have bag scanning right before you get on the plane.

Are Hydroflasks Allowed in Checked Bags?

Blue Travel Luggage

Yes, hydro flasks are allowed in checked bags. Your hydro flask can even be full if you want because there are no restrictions on liquid in checked luggage.

However, you’re unlikely to want to risk any spillage into your luggage. Pack hydro flasks in your checked luggage to maximize carry-on luggage space unless you plan on using your hydro flask bottle as a reusable water bottle at the airport.
