Yes, you can bring a mug (ceramic or glass) on a plane in both carry-on and checked luggage, provided it is empty when passing through airport security.

Let’s dive right in.

Can You Bring a Mug Through TSA Security?
According to the TSA (Transportation Security Administration )you can bring a mug or thermos through the security checkpoint without any issues.
You can empty your mug or thermos when going through the security checkpoint and refill after that, because liquids are limited in the cabin, no more than 3.4 oz and should be carried in a sealed plastic bag.
Typically coffee cups are around 12 oz / 350 ml which is more than the allowed quantity of liquids.
Here is what the TSA says about coffee thermos and mugs on planes.
I wanted to find more answers from the TSA social media.
This user wanted to bring her empty travel mug with metal straw in her carry-on.
The TSA team replied that empty metal, insulated water bottles and mugs of all size are allowed in carry-on bags.
Metal straws are also allowed.
Can You Bring a Mug In a Carry-on?
Whether you are flying United, American, or Delta Airlines you can bring your mug on a plane in your carry-on bag.
You can pack a glass mug or any kind of mug, and you don’t need to remove it from your carry-on bag or personal item or place it in a bin for additional screening when you go through airport security.
All kinds of mugs are allowed on planes, but they should be empty until you pass the security checkpoint:
- Ceramic mug
- Crockery mug
- Plastic coffee mugs
- Glass mug
- Empty coffee mug
- A Yeti mug
- Travel mug
This passenger asked the TSA on X if he could bring his 20-ounce Yeti mug on the plane.
The TSA customer service replied, “Empty insulated water bottles of all sizes are allowed in carry-on bags.”

Can You Bring a Mug In Checked Baggage?
You can pack mugs or coffee thermoses in your checked baggage, but it’s not advisable if they are easy to break or are one of your favorite souvenir mugs.
It is better to bring your mug inside your personal item or carry-on bag generally, any bag that you can take with you on board.
There is also the chance that your checked baggage could be lost or delayed.
If you put your mug in your checked bag, there is a higher chance that it may break, or your luggage could be lost or delayed.
So, if you don’t want to carry your mug in your hand, your carry-on bag or personal item is the best place to pack it.
Can You Bring a Coffee Mug On a Plane?
It may take you a little effort to find your favorite coffee mug, which is why you’re asking if you are allowed to take it with you on your flight and here is the good news.
If you are traveling on a domestic flight, you are permitted to pack a coffee mug in your hand luggage or just bring it on board in your hand as you board the airplane.
Just ensure that you finish your drink or empty your mug before the security checkpoint. Then you can refill your mug afterward.
Because liquids have restrictions, the amount allowed in the cabin is limited, as stated above, so a filled coffee mug cannot go through the security checkpoint.
Can You Bring a Travel Mug On a Plane?
Whether you want to bring a traditional travel mug, you can place it in your bag without any problem.
Just make sure it is secured, protected at all times, and easy to reach in case airport security asks you to remove it.
If you take an insulated travel mug, which is more popular and designed for on-the-go activities, there is a higher chance that airport security may ask you to take it out of your bag for a simple inspection.

Final Thoughts
You can bring almost nay type of mugs on a plane in your carry-on as well as in your checked baggage, provided they are empty from any drinks before you go through the security checkpoint.
Then you can refill your mug with coffee or any drink at the airport.
However, insulated mugs may be harder to scan, so they may require a physical inspection.
Make sure your mug is organized in your bag and easy to reach.
I hope this helps
Happy travels
