Can You Bring Alcohol on a Plane? TSA Carry-On and Checked Bag Rules

Where these numbers come from

Alcohol rules depend on strength, measured as alcohol by volume (ABV). Federal hazmat rules split drinks into three groups: 24 percent or less, over 24 percent up to 70 percent, and over 70 percent. The group tells you how much you may pack in checked luggage.

Beer, wine and most ciders fall in the first group, so checked bags have no quantity limit from TSA or FAA. The limit you actually hit is airline weight. Twelve bottles of wine weigh roughly 40 to 45 pounds, which can push a bag past 50 pounds. See the bag cost calculator for fees.

Spirits at 40 percent ABV sit in the middle group. They must be in unopened retail packaging, and you may carry at most 5 liters per passenger. Example: six 750 ml bottles total 4.5 liters, so you are under the cap. Seven bottles is 5.25 liters, which is over it.

The third group is banned outright. Anything over 70 percent ABV, which is over 140 proof, cannot travel in either bag. That includes 151-proof rum and high-strength grain alcohol. Hazmat limits are federal, and airlines can be stricter.

In the cabin, each container must be 3.4 oz or smaller and fit in the quart bag, so miniatures work and full bottles do not. You also may not drink your own alcohol on board. FAA regulations allow drinking only when the airline serves it.

Airport purchases work differently from home stock. Bottles bought after security are usually allowed on board because they have been screened, although a connecting flight in another country may require a sealed bag. Keep the bag sealed until you reach your final stop and keep the receipt visible.

Breakage and labeling deserve a note. The 5 liter limit applies to unopened retail packaging, so a half-full bottle of whiskey is a gray area and may be refused. Keep receipts for bottles bought duty-free or at a distillery, because customs officers at your destination can ask about quantity and value. Some states and countries also cap how much alcohol you may import without a permit or duty.

Abroad, check customs and import allowances at the destination. The 5 liter cap is a US aviation rule, not an import allowance. See the wine page for bottle packing, and the Can I bring it? finder for other items.
