Bringing an empty thermos through airport security is generally permitted, although regulations may vary depending on the airport and country. In the United States, the Transportation Security Administration (TSA) allows empty drink containers, including thermoses, to be carried in carry-on baggage. However, it is important to ensure that the thermos is completely empty before passing through security to avoid any inconvenience. Some travelers choose to fill their empty thermoses with ice or water after clearing security, which can be more convenient and environmentally friendly than purchasing bottled water inside the airport. It is worth noting that there are usually no restrictions on the amount of liquid carried on domestic flights in Australia, and some airports outside the US allow liquids without limits. Nevertheless, it is always advisable to check the specific regulations of the departure airport and the airline before traveling.

What You'll Learn

Empty thermoses are allowed through airport security
If you're wondering whether you can bring an empty thermos through airport security, the answer is yes. Empty drink containers, including thermoses, are allowed through security checkpoints. However, it's important to ensure that your thermos is completely empty before passing through security. Some travellers have shared their experiences of being asked to return and empty their thermoses if they still contained liquid.
To avoid any inconvenience, it's recommended to empty your thermos before arriving at the airport. Once you've passed through security, you can fill up your thermos at a water fountain or another source. This is a common practice among travellers who want to stay hydrated during their flight and avoid using plastic cups provided by the flight attendants.
It's worth noting that, while empty thermoses are allowed, there are restrictions on bringing liquids through airport security. The TSA, for example, has a 3.4-ounce (100 ml) limit on liquids, gels, and aerosols in carry-on bags. This means that if you plan to fill your thermos with a beverage other than water, you should ensure it complies with the liquid restrictions.
Additionally, some airports may have specific guidelines regarding beverage containers. For example, Canberra Airport in Australia requires that beverage containers, including thermoses, are sealed and submitted for X-ray screening. It's always a good idea to check the regulations of the specific airport you're travelling through to ensure you're following their guidelines.
In summary, empty thermoses are generally allowed through airport security. Just make sure your thermos is empty before reaching the security checkpoint, and be mindful of any additional restrictions or guidelines that may be in place at your particular airport.

However, it is important to remember that the thermos must be empty when passing through security. If it is not, you may be forced to go back and start the security process again.
There are a few things to keep in mind when bringing an empty thermos through airport security. Firstly, it is a good idea to choose a leak-proof design to prevent any spills in your bag.

It is also worth noting that some airports have different rules regarding liquids. For example, there is no restriction on the amount of liquid that can be brought on domestic flights in Australia. However, in the US, the TSA has a 3.4-ounce (100 ml) rule for liquids, gels, and aerosols in carry-on bags.

Hot food is allowed in thermoses
Bringing an empty thermos through airport security is generally permitted, and many travellers report doing so without any issues. However, it is important to remember that regulations can vary depending on the airport and the country. While an empty thermos is typically allowed, any remaining liquid inside may require you to go back and re-queue for security screening. Therefore, it is advisable to ensure your thermos is completely empty before proceeding through security.
Now, let's specifically address bringing hot food in a thermos through airport security. While there is limited official information available, some travellers have shared their experiences and insights. It appears that bringing hot food in a thermos on a plane is generally acceptable, provided it is not a liquid. Solid foods, such as chilli, stews, and other one-pot meals, can be transported in a thermos flask and are not restricted on domestic flights in Australia. This suggests that bringing hot food in a thermos can be permissible, especially if it is a solid meal rather than a soup or beverage.
Additionally, some airports may require sealed containers, such as flasks or thermoses, to be submitted for X-ray screening. This is to ensure that the contents do not cause damage to the X-ray apparatus. So, while you may be able to bring hot food in a thermos, it might need to undergo additional screening procedures.
It is worth noting that some travellers have expressed concerns about the limited availability of appealing meal options during long flights or when arriving at their destination late at night. In such cases, bringing a hot meal in a thermos can be a practical solution to ensure a satisfying dining experience while travelling.
Lastly, remember to always check with the specific airline and airport you are travelling through, as regulations can vary, and it is essential to comply with their guidelines to ensure a smooth journey.
