In this article, we’ll provide a detailed explanation of the rules and regulations surrounding bringing a coffee mug in your carry-on, as well as a few tips on how to make sure you’re compliant with TSA standards. So, grab your favorite mug, and let’s get started!

Can i bring a coffee mug in my carry-on?

You’ll be relieved to learn that the Transportation Security Administration (TSA) says the answer is okay, providing the mug is correctly packed to adhere to specific requirements before boarding the aircraft and depending on the carrier, such as whether it’s a domestic or international flight.

  • Carry-On Bags: Yes
  • Checked Bags: Yes

You may take empty drink containers through the checkpoint and fill them afterward.

All of these mugs are permitted on airplanes:

The TSA advises that you can empty your mug or thermos at the security checkpoint and then refill it later because liquids are only allowed in the cabin in quantities of 3.4 ounces or less and must be transported in a sealed plastic bag.

Packing your coffee mug in your carry on

Put the mug in your carry-on’s front pocket so it can be quickly checked.

If your coffee mug has a lid, take it off and stow it separately so that security can quickly scan your bag and verify that it is empty. If the lid is left on, security won’t be able to determine whether the mug is open, which could result in a problem.

No need to worry if you are flying with a glass coffee cup because the TSA does permit glass goods in carryons. To prevent problems, you may travel with unbreakable items instead, like plastic coffee mugs, as if breakable items were to end up in your bag, they might cause problems with security because they could be used as weapons.

If you bring a glass mug, wrap it tightly to prevent it from breaking in transit and causing security problems. Additionally, make sure the glass adheres to your airline’s weight regulations.


Nearly all varieties of mugs are permitted in your carry-on and checked baggage as long as they are empty when you pass through security. Once you know these rules and strictly adhere to them, you are set to go! So take a drink and enjoy your coffee!
