Yes — but the limits depend on where the bottle rides and how strong it is. The 100ml carry-on rule, the 5-litre checked-bag cap, the 70% ABV ban and duty-free traps, explained.

Can you take alcohol on a plane? Yes — but the rules depend on where the bottle travels and how strong it is. In your carry-on, alcohol follows the standard liquids rule: containers of 100ml (3.4oz) or less inside your single resealable liquids bag, whatever the strength. In checked luggage, drinks under 24% ABV (nearly all beer and wine) face no dangerous-goods quantity limit; spirits between 24% and 70% ABV are capped at 5 litres per passenger in unopened retail packaging; and anything over 70% ABV (140 proof) — including some overproof rums — is banned from both cabin and hold. Duty-free bought airside is the exception to the carry-on limit, with its own catch at connections. And whatever you carry, drinking your own alcohol on board is prohibited almost everywhere: on US carriers, federal rule 14 CFR 121.575 says only the crew may serve it.
How much alcohol can you take in hand luggage?
At the security checkpoint, alcohol is just another liquid. That means containers no larger than 100ml/3.4oz, all fitting comfortably in one quart-sized (roughly one-litre) transparent bag. Miniatures bought in a shop before the airport are fine within that limit; a full-size bottle from home is not, regardless of how much is left inside it.
The same screening logic covers other consumables too — see our guide to what food you can bring on an international flight. And if you are flying through the UK, where some airports have new scanners and some do not, the 100ml liquid rule still applies at most UK airports, so pack to the strictest standard on your route.
What about duty-free bottles and connecting flights?
Bottles bought airside, after security, can exceed 100ml because they enter the cabin already screened. The trap is the connection: if you change planes and must re-clear security at the transfer airport — standard when arriving into the US, and common elsewhere — an unprotected litre of gin becomes an oversized liquid and will be binned.
The workaround is the security tamper-evident bag (STEB): an ICAO-standard sealed transparent bag, packed by the shop with the receipt visible inside (generally valid for 48 hours). Screeners at the connecting checkpoint can accept sealed STEBs with over-100ml duty-free liquids — but only if the seal is intact and the bottle screens clear. Open the bag mid-journey and the exemption dies. The same applies on the way home: buy on the final leg where possible. Our explainer on how duty-free shopping actually works covers STEBs and allowances in more depth.
Alcohol in checked luggage: the ABV bands
Aviation dangerous-goods rules (reflected in TSA/FAA guidance and airline policies such as JetBlue's) sort alcohol into three bands by strength:
| Strength | Carry-on | Checked bag | Notes |
|---|---|---|---|
| Under 24% ABV (beer, most wine) | Only in ≤100ml containers, or sealed duty-free | No dangerous-goods limit | Your bag's weight allowance is the real cap |
| 24–70% ABV (most spirits, fortified wine) | Only in ≤100ml containers, or sealed duty-free | Max 5 litres per passenger | Must be in unopened retail packaging |
| Over 70% ABV / 140 proof (overproof rum, some grain spirits) | Banned | Banned | Treated as a flammable dangerous good |
Remember that 5 litres of spirits plus glass weighs 8–9kg — check your airline baggage allowance before you load up. Pack bottles in the middle of the case, wrapped in clothing or padded sleeves, each inside a sealed plastic bag in case of breakage, and never against the shell of the suitcase.
Can you drink your own alcohol on the plane?
No. On US airlines, 14 CFR 121.575 states that no person may drink any alcoholic beverage aboard an aircraft unless the operating carrier served it — and airlines must report violations and visibly intoxicated passengers to the FAA within five days. Fines for alcohol-related disturbances have reached over $40,000 in recent enforcement, alongside possible arrest and airline bans. UK and EU carriers apply the same principle through their conditions of carriage, and crews everywhere may refuse to serve anyone appearing intoxicated. JetBlue — long cited as the airline that would serve passengers their own bottle — now states plainly that you are not allowed to consume your own alcohol on board.
Dry airlines and dry destinations
Several carriers serve no alcohol at all, including Saudia, Kuwait Airways and Royal Brunei. Policies on carrying it differ sharply: Saudia prohibits even transporting alcohol on its flights, while Royal Brunei lets non-Muslim passengers consume their own on international sectors — though leftovers are confiscated on arrival in Brunei.
Destination rules matter as much as airline rules. The Maldives bans visitors from importing any alcohol — customs explicitly warns against buying duty-free en route, as bottles are confiscated on arrival (resorts serve legally imported drinks under licence). Elsewhere, duty-free import allowances typically run to one or two litres of spirits per adult; exceed them and you owe duty, so check your destination's customs page before checkout.
Frequently asked questions
Can you take alcohol on a plane in your hand luggage?
Yes, in containers of 100ml/3.4oz or less inside your liquids bag, at any strength up to 70% ABV. Larger bottles are only allowed if bought airside as duty-free — sealed in a tamper-evident bag with the receipt if you have a connection.
How much alcohol can I put in a checked bag?
Drinks under 24% ABV have no dangerous-goods limit — only your weight allowance. Spirits between 24% and 70% ABV are capped at 5 litres per passenger in unopened retail packaging. Anything over 70% ABV is banned entirely.
Can I drink my own duty-free alcohol during the flight?
No. US federal rule 14 CFR 121.575 permits only crew-served alcohol, and UK/EU carriers impose the same ban in their conditions of carriage. Penalties range from confiscation to fines of tens of thousands of dollars and airline bans.
Can I take duty-free alcohol through a connecting airport?
Only if it stays sealed in the security tamper-evident bag (STEB) with the receipt visible, and the connecting checkpoint accepts STEBs — standard practice at US re-screening. If the seal is broken, over-100ml bottles will be confiscated.
Which countries won't let me bring alcohol in?
The Maldives confiscates all arriving alcohol, including duty-free. Other destinations restrict rather than ban it, with typical allowances of one to two litres of spirits; always check the destination customs website before buying.
