TSA Hydro Flask

The TSA does not mention Hydro flaks on its website but obviously they have no issues with to take an empty hydro flask through the airport security checkpoint.

If you want to bring a hydro flask filled with a drink through the security checkpoint the security agent won’t let you do that.

Only 3.4 oz / 100 ml containers are allowed in carry-on luggage and they need to be placed inside a quart size bag.

In fact not only the TSA that has liquid restrictions but also most international airlines and airports.

So it is better to empty your Hydro flask from any drinks at the airport or before heading to the airport; and you can fill it up after you pass the security point.

I checked Twitter to find more answers from the TSA.
