Can I Bring Alcohol on a Plane?

Key restrictions

Carry-on alcohol follows the 3-1-1 rule — containers of 3.4oz (100ml) or less in your quart bag.

Duty-free alcohol over 100ml flies in the cabin only in a sealed tamper-evident bag with receipt.

Checked bags: alcohol between 24% and 70% ABV limited to 5L per passenger, in unopened retail packaging.

Alcohol over 70% ABV (140 proof, e.g. some overproof rums) is banned from all baggage.

Beverages under 24% ABV (beer, wine) have no quantity limit in checked bags.

Drinking your own alcohol onboard is prohibited — only crew-served alcohol is allowed.

Why this matters

Alcohol triggers three different rule sets at once: the liquids rule at security, hazardous-materials limits in checked baggage (high-proof alcohol is flammable), and customs allowances at your destination. A traveler bringing home a case of spirits can clear the first two and still owe duty at the border. Sorting the rules by strength and by bag makes the whole picture manageable.

Restrictions

Carry-on: alcohol is a liquid, so only containers of 3.4oz (100ml) or less in your quart bag — fine for miniatures, useless for full bottles. Duty-free purchases are the exception: bottles sealed airside in a tamper-evident bag with the receipt can exceed the limit, though a second screening at a foreign connection can still reject them.

Checked baggage, sorted by alcohol strength:

Under 24% ABV (beer, wine, cider): no quantity limit under aviation rules — packing weight and customs duty are your real constraints.
24%–70% ABV (most spirits and liqueurs): up to 5 liters per passenger, in unopened retail packaging.
Over 70% ABV (140+ proof, like some overproof rums and grain alcohol): prohibited in all baggage.

Wrap checked bottles well — pressure and handling break glass, and one broken bottle ruins a suitcase.

Onboard, you may not drink alcohol you brought yourself; only crew-served drinks are legal. And remember customs: most countries admit only 1–2 liters duty-free, far below what aviation rules let you pack.

What the official guidance says

The FAA's PackSafe guidance sets the checked-baggage framework: no limit below 24% ABV, 5 liters per passenger in retail packaging between 24% and 70%, and a complete ban above 70%. TSA applies the 3-1-1 rule to alcohol in carry-on and defers to FAA rules for checked bags. Airlines can be stricter, and a few prohibit alcohol in checked luggage on certain routes, so confirm with your carrier for large quantities.

Frequently asked questions

Can I bring a bottle of wine or whiskey in carry-on?

Not through security — a standard 750ml bottle is far over the 100ml limit. The exceptions are duty-free bottles bought airside, sealed in a tamper-evident bag with receipt, or bottles purchased after the checkpoint. Otherwise, full-size bottles go in checked luggage.

How much alcohol can go in checked baggage?

Depends on strength. Under 24% ABV (wine, beer): no federal limit. Between 24% and 70% ABV (most spirits): up to 5 liters per passenger in unopened retail packaging. Over 70% ABV: prohibited entirely. Destination customs allowances are separate and usually much lower.

Can I drink alcohol I brought onto the plane?

No. US regulations prohibit passengers from drinking alcohol that was not served by the crew, and most countries have equivalent rules. Bottles you carry on must stay sealed until you land — drinking your own can mean fines and airline bans.
