You can fly with a 12-pack of beer, but it must be in your checked luggage, as individual cans or bottles exceed the 3.4oz (100ml) liquid limit for carry-on bags. According to TSA and international 2026 regulations, there is no federal limit on the amount of alcohol under 24% ABV (like beer or wine) you can pack in checked bags, though you must stay within your airline's weight limits. To prevent a "beery mess," you should wrap each can in bubble wrap or a "WineSkin" and place the entire pack in a heavy-duty, leak-proof plastic bag before nesting it in the center of your suitcase surrounded by soft clothes. Note that while flying domestically is straightforward, international travel may require you to pay customs duties if you exceed the destination country's duty-free allowance, which is often as low as two liters for beer.
