Bringing alcohol on the plane in your carry-on is limited as any other liquid - so no more than 100ml. In checked bags, your limits depend on alcohol content. If the alcohol by volume is less than 24 percent (for example beer and wine) there are no limits on how much alcohol you can pack. If the alcohol by volume is between 24 and 70 percent you’re limited to 5 liters. Alcohol above 70% is prohibited in both cabin baggage and checked luggage.
Please note that airport security officers may decline taking an item on a plane if it may cause a threat.
Rules may slightly differ depending on the airport and circumstances.
