Many people have that specific question, can you bring little bottles of liquor on a plane?Bringing small bottles of spirits on an aircraft is subject to rules and regulations. The Transportation Security Administration (TSA) enables travellers to carry liquids in containers 3.4 ounces (100 millilitres) or less in their carry-on luggage until September 2021, according to my understanding. These containers must be provided individually for security screening in a transparent, quart-sized plastic bag. It is important to remember, however, that airlines may have their own laws regarding the drinking of alcohol on board, therefore it is best to verify with the individual airline before attempting to bring alcohol on board.
