Liquor bottles are allowed on planes, but there are certain rules and restrictions that must be followed.
If you want to bring alcohol on a plane, it must be in your checked baggage, not your carry-on bag. The alcohol must also be in its original, unopened container, and the container must be securely wrapped in a plastic or other suitable material to prevent breakage.
Additionally, the amount of alcohol you can bring on a plane is limited by the airline and by government regulations. In the United States, for example, the TSA (Transportation Security Administration) allows passengers to bring one quart-sized bag of liquids, aerosols, gels, creams, and pastes in their carry-on bag, and each container must be 3.4 ounces or less.
It's also important to note that some countries may have different regulations regarding the transportation of alcohol, so it's a good idea to check with the airline and the destination country's customs regulations before bringing any alcohol on board.
