Based on the regulations set forth by the Transportation Security Administration (TSA), it is permissible for passengers to transport miniature alcohol bottles on an airplane. The rules governing their transport depend on whether they are placed in carry-on or checked baggage. For carry-on luggage, these bottles are subject to the same restrictions as all other liquids, gels, and aerosols.
In accordance with the TSA's 3-1-1 liquids rule, each container of liquid must be 3.4 ounces (100 milliliters) or less. Since standard miniature liquor bottles are typically 50ml, they fall well within this size limitation. All such containers must be placed together in a single, clear, quart-sized, resealable bag. Furthermore, there are restrictions based on the alcohol content. Alcoholic beverages with more than 70% alcohol by volume (over 140 proof) are forbidden in both carry-on and checked luggage.
While passengers are permitted to bring these miniature bottles through security and onto the aircraft, it is crucial to understand the regulations regarding consumption. Federal Aviation Administration (FAA) regulations strictly prohibit passengers from consuming alcohol on board an aircraft unless it is served to them by the airline's flight crew. Therefore, while you can transport your own mini alcohol bottles, you are not permitted to open or drink them during the flight. This distinction between permissible transport and prohibited consumption is a key aspect of aviation regulations.
