can you bring liquor on a plane:- You may carry alcohol on an aircraft, but there are certain restrictions to take into account. As long as it is in sealed bottles and complies with the airline's size and quantity restrictions, alcohol is permitted in checked baggage. However, as some limitations can be in place, it's crucial to review the particular policies of the airline and the country of travel. Additionally, the Transportation Security Administration's (TSA) liquid limits apply to alcohol carried in carry-on luggage.
