 Are tumblers allowed on planes?

Yes, tumblers are generally allowed on planes, but there are some restrictions and guidelines that you should be aware of before bringing them on board.

According to the Transportation Security Administration (TSA) guidelines, tumblers made of metal, glass, or ceramic are allowed in carry-on bags, but they may be subject to additional screening. Tumblers made of plastic or other materials are also allowed in carry-on bags.

If you plan to bring a tumbler filled with liquid, it must be empty before going through security. Once you pass security, you can fill your tumbler with your beverage of choice. It is important to note that some airlines may have their own restrictions or policies regarding tumblers, so it's a good idea to check with your airline before traveling.

It's also worth noting that some tumblers may not fit in the cup holders on airplanes, so you may need to hold onto your tumbler during the flight or place it in the seatback pocket. Additionally, if you plan to use your tumbler for hot beverages, be sure to use caution as turbulence can cause spills or burns.
