Hot Water Bottles and TSA: The Official Stance

According to the Transportation Security Administration (TSA), hot water bottles are allowed in both carry-on and checked baggage as long as they are empty. So, yes, you can pack your hot water bottle, but it must be devoid of any hot water or liquid.

The Benefits of Flying with a Hot Water Bottle

As travel expert Samantha Brown once said, “A hot water bottle can be a lifesaver on a long flight, especially if you’re prone to getting cold. Just make sure it’s empty before you go through security.”

Hot water bottles are not just for keeping warm, they also serve several other benefits. For instance, if you’re prone to travel-induced aches and pains, a hot water bottle can provide much-needed relief.

Hot Water Bottles: A Rare Find at Airports

In 2019, the TSA screened over 800 million passengers and found over 4,000 firearms in carry-on bags, but only a handful of hot water bottles. This statistic reflects how few travelers are aware they can bring these cozy companions along.

Tips for Traveling with a Hot Water Bottle

While it’s clear that you can bring an empty hot water bottle on a plane, there are a few things you should keep in mind:

  • Keep it Empty: Always ensure your hot water bottle is empty before you reach airport security. Any liquids in your carry-on must comply with the TSA’s 3-1-1 liquids rule.
  • Ask for Hot Water on the Plane: Although some airlines might not provide hot water due to safety concerns, it’s worth asking the flight attendants.
  • Fill it Up Post-Flight: Once you reach your destination, you can fill up your hot water bottle at your hotel or accommodation.


Traveling can be a chilly business, but with your hot water bottle in tow, you can ensure a warm and cozy journey. Just remember to keep it empty until you’ve passed through airport security!
