can you fly with a thermos cup

If you like to take your favorite beverage hot or cold with you on the go, you might be wondering if you can take your trusty thermos with you when you fly. Unfortunately, the answer is not as simple as a simple “yes” or “no”.

To find out if you can fly with a thermos, you need to consider several factors.

First, you need to consider the material of your thermos. Most thermos cups are made of stainless steel or plastic. If your thermos is made of stainless steel, you should be able to take it on the plane, because it is not a prohibited material. However, if your thermos is made of plastic, you’ll want to make sure it’s BPA-free to comply with TSA regulations.

Second, you need to consider the size of your thermos. The TSA has clear guidelines on the amount of liquids you are allowed on board. According to TSA regulations, you can bring quart-sized liquids, sprays, gels, creams and ointments in your carry-on luggage. The liquid capacity of each container should not exceed 3.4 ounces (100 milliliters). If your thermos is larger than 3.4 oz, you can empty it or check it in your luggage.

Third, you need to consider what’s in your thermos. If you’re carrying hot beverages, you’ll want to make sure your thermos has a tight-fitting lid to prevent spills. Also, you need to pay attention to the temperature of your hot drinks as it can sometimes trigger additional security checks. If you’re bringing a cold drink, you’ll want to make sure it’s completely frozen or pureed, as TSA doesn’t allow you to bring ice cubes.

Finally, you need to consider the airline you’re flying with. While the Transportation Security Administration (TSA) has guidelines on what you can and can’t bring on board, each airline may have its own set of rules and regulations. For example, some airlines may not allow you to bring any liquids on board, while others may allow you to bring a full-sized thermos as long as it fits in the overhead bin.

In short, you can fly with a thermos cup, but you need to pay attention to the material, size, content and airline regulations. Taking some time to research and prepare beforehand can save you unnecessary trouble and inconvenience during your flight. With these tips in hand, you can now enjoy your favorite beverage, hot or cold, even while flying to your next destination!
