In the U. S. , alcoholic beverages containing less than 24% alcohol, such as beer and wine, are not restricted as hazardous materials by the Federal Aviation Administration.
If you have a connecting flight after reentering the U. S. , however, you will have to go through security again and the duty-free alcohol will then be subject to the 3. 4 ounces or 100 milliliter regulation for liquids in carryon luggage.
