If you're planning to bring a thermos through airport security, you'll be glad to know that it's generally permitted as long as it's empty. This is in line with the TSA's 3-1-1 liquids rule, which prohibits liquids in containers larger than 3.4 ounces (100 milliliters) in carry-on luggage. However, there may be exceptions for certain foods, such as mashed potatoes, which may not be allowed through security even in a thermos. It's also important to note that some airports have different regulations, so it's always a good idea to check with the specific airport or country's guidelines before your travel.

What You'll Learn
Empty thermoses are allowed
Yes, you can bring an empty thermos through airport security. According to the TSA, empty drink containers are allowed to pass through security checkpoints. This includes empty water bottles, empty travel mugs, and empty coffee thermoses.
However, it's important to note that the thermos must be completely empty before going through security. If it is not empty, you may be forced to go back, empty it, and then go through security again. In some cases, non-empty thermoses may be subjected to further inspection.
Once you have passed through security with your empty thermos, you can fill it with hot or cold liquids. This is a great way to avoid using single-use plastic water bottles, as thermoses are perfectly safe to bring on planes. They will not explode due to air pressure or any other reason.
In addition to liquids, you can also bring hot solid food through airport security in a thermos. However, the food must be solid, so soups and stews are not allowed. It's important to note that the interpretation of "solid food" can vary. For example, mashed potatoes are not considered solid food, while solid potatoes are. If you are bringing food through security in a thermos, it's a good idea to let the TSA agents know what's inside and why.

Liquid restrictions
You can bring an empty thermos through airport security without any issues. However, if you try to bring a filled thermos through security, you will be forced to go back, empty it, and go through security again. This is due to the TSA's 3-1-1 liquids rule, which states that liquids, gels, creams, and pastes must be in containers of 3.4 ounces (100ml) or less to be brought onto a plane. These items must be placed in a quart-sized bag and separated from your carry-on baggage.
The 3-1-1 liquids rule applies to all types of liquids, including water, coffee, alcoholic beverages, and even liquid baby formula or breast milk. Solid foods, such as sandwiches, potato chips, and candy, are allowed on planes, while spreadable foods like peanut butter, cottage cheese, honey, or Nutella are only permitted in checked bags and must be in containers larger than 3.4 ounces.
There are some exceptions to the 3-1-1 liquids rule. For example, travellers are allowed to bring duty-free liquids in secure, tamper-evident bags of more than 3.4 ounces in their carry-on bags if they are travelling to the United States with a connecting flight. Medication is another exception, and may be visually screened, X-rayed, or tested for traces of explosives. In some cases, travellers may be asked to open the container for a vapor analysis.
It is important to note that the final decision on whether an item is allowed through the checkpoint rests with the TSA officer. While most solid food items are allowed in carry-on luggage, spreadable foods and liquids in containers larger than 3.4 ounces are not permitted and must be packed in checked baggage.

Solid food in thermoses
Solid foods are generally allowed on planes, but there are some restrictions. The Transportation Security Administration (TSA) prohibits spreadable foods like peanut butter, cottage cheese, honey, and Nutella chocolate spread in carry-on luggage. These foods are only allowed in checked bags if they are in containers larger than 3.4 ounces (100 milliliters). Other spreadable foods and liquids such as salsa, creamy cheese, dips, jams, and preserves are also subject to the 3-1-1 rule and can only be carried on in containers less than 3.4 ounces.
Solid foods that are allowed on planes include potato chips, sandwiches, candy, hard cheese, frozen seafood, and fresh eggs. Pies and cakes are also allowed through security.
When it comes to bringing solid food in a thermos through airport security, there are a few things to keep in mind. Firstly, the thermos must be completely empty before passing through security. This is because the TSA's 3-1-1 liquids rule prohibits liquids, including water, in containers larger than 3.4 ounces. However, once you have passed through security, you can fill your thermos with hot water, prepare your food, and then close the lid to keep the contents hot. Suitable foods for a thermos include soup, baked beans, pasta, ravioli, and lasagna.
It is important to note that even if an item is generally permitted, it may be subject to additional screening or may not be allowed through the checkpoint if it triggers an alarm during screening, appears tampered with, or poses security concerns. The final decision rests with the TSA officer at the checkpoint. Therefore, it is recommended to check the latest regulations and guidelines from the TSA and your specific airline before packing solid food in a thermos for air travel.

Scanning and inspection
When it comes to bringing a thermos through airport security, it's important to be aware of the specific rules and regulations to ensure a smooth and hassle-free experience. Here's what you need to know about scanning and inspection:
Empty Thermos:
First and foremost, it is essential to ensure that your thermos is completely empty before passing through security. This is a standard requirement at most airports. Any liquid or beverage inside the thermos must be finished or discarded before entering the security screening area. This rule applies to all types of thermoses, including stainless steel water bottles, coffee thermoses, and travel mugs. It is worth noting that some airports may be more lenient with this rule, but it is always best to err on the side of caution.
X-Ray Inspection:
Once you reach the security checkpoint, your empty thermos will typically undergo X-ray screening. Place the thermos in a separate tray or container to be scanned. The X-ray machines will help security officers inspect the item for any traces of liquid or prohibited substances. In some cases, the unique shape or material of your thermos may trigger further inspection. Security officers may want to take a closer look inside your thermos to ensure it is indeed empty and does not contain any prohibited items.
Declaration:
To streamline the inspection process, it is advisable to proactively declare the presence of your thermos to the TSA agents at the security checkpoint. Inform them that you are carrying an empty thermos, and if applicable, mention any unique features or contents that may raise questions. For example, if you intend to carry hot solid food in your thermos, let the officers know. This proactive approach can help prevent any misunderstandings and facilitate a smoother inspection process.
Solid Food Considerations:
When packing solid food in your thermos, be mindful of the TSA guidelines. Solid foods, such as sandwiches, potato chips, and candy, are generally allowed in carry-on luggage. However, mashed or spreadable foods, such as mashed potatoes, peanut butter, or similar canned foods, are not permitted in carry-on bags. These semi-solid or liquid-like substances must be packed in checked baggage. It's important to consider the consistency and classification of your food items to comply with TSA regulations.
Refilling Options:
After successfully passing through security with your empty thermos, you can refill it with your preferred beverage. Many airports provide water fountains or beverage options near the departure gates, allowing you to fill your thermos before boarding your flight. Additionally, if you plan to bring hot food in your thermos, you may need to consider accessing hot water or heating options at the airport or onboard the aircraft to maintain the temperature of your meal.
By adhering to these guidelines and being cooperative during the scanning and inspection process, you can confidently bring your thermos through airport security. Remember to stay informed about any specific regulations or updates from the TSA or local airport authorities to ensure a seamless travel experience.

Filling after security
You can bring an empty thermos through airport security. According to TSA regulations, empty drink containers are allowed through security checkpoints, and you can fill them afterward. This is because the TSA's 3-1-1 liquids rule does not allow liquids in containers larger than 3.4 oz (100 ml) in carry-on luggage.
Once you have passed through security, you can fill your empty thermos at a water fountain at your arrival airport. If you are travelling with a baby or toddler, you can fill your thermos with liquid for the baby. If you are taking an overnight flight, you can fill your thermos with coffee prior to boarding, so you have coffee to enjoy when you wake up before landing. Alternatively, you can fill your thermos with ice, although there are different rules for this in different countries. In the US, ice must be completely frozen with no moisture evident. In Canada, ice is only allowed in amounts less than 100 ml.
