TSA Travel Tips Tuesday - Traveling With Alcoholic Beverages
Whether travelers are taking them on the road, or bringing them back from their adventures,
alcoholic beverages are item that travelers often pack in their baggage. This is fine as long as a few guidelines are followed when packing.
Carry-on Baggage
Travelers may carry as many 3.4 ounce bottles of liquid (mini bottles of liquor are 1.7 ounces) that fit comfortably in one, quart sized, clear plastic, zip-top bag. Comfortable means that the bag will seal without busting at the seams. One bag is permitted per passenger.
Liquids (including alcohol) purchased after clearing the security checkpoint are permitted on the aircraft.
I assume that means you can pack a 1 qt zip lock bag with 100ml bottles of Jack Daniels. That's Carry on!
FAA regulations state that “No person may drink any alcoholic beverage aboard an aircraft unless the certificate holder operating the aircraft has served that beverage.”
Checked Baggage
Any amount of alcohol greater than 3.4 ounces must be packed in checked baggage.
Alcoholic beverages with more than 70% alcohol content (140 proof), including 95% grain alcohol and 150 proof rum, cannot be packed in checked luggage.
Travelers may take up to five liters of alcohol with alcohol content between 24% and 70% per person as checked luggage if it’s packaged in a sealable bottle or flask.
Alcoholic beverages with less than 24% alcohol content are not subject to hazardous materials regulations.

Alcoholic beverages purchased in duty-free shops are subject to duty and federal excise tax when accompanying you into the United States. Note: Federal excise tax rates are for informational purposes only as actual tax or fee may vary according to a person's circumstances.
There is no federal limit on the amount of alcohol a traveler may import into the U.S. for personal use, however, large quantities might raise the suspicion that the importation is for commercial purposes,
