Can You Bring Wine on a Plane? TSA, FAA and Customs Rules

Yes, you can bring wine on a plane, but full bottles belong in your checked bag. TSA allows only 3.4 ounces (100 ml) of liquid per container in carry-on bags, so a 750 ml bottle can’t go through the checkpoint. In checked luggage, wine is easy: TSA puts no limit on drinks of 24% alcohol or less, which covers table wine and fortified wines like Port. Flying home from abroad adds US customs rules on top. Here is what each agency says, with the dates we checked, and how to pack bottles so they arrive in one piece.

The rules at a glance

Where	Table wine (24% alcohol or less)	Stronger drinks (over 24%, up to 70%)	Over 70%
Carry-on	Only containers of 3.4 oz (100 ml) or less, in your quart-sized liquids bag	Same	Outside the FAA passenger exception
Checked bag	No TSA limit	Up to 5 liters per passenger, in unopened retail packaging	Outside the FAA passenger exception
On board	You may not drink your own alcohol; only what the airline serves	Same	Same

The table combines TSA’s alcoholic beverages page (last updated February 20, 2025), TSA’s liquids rule and the FAA’s PackSafe page for alcohol (last updated April 13, 2026), all checked October 29, 2026.

Wine in carry-on bags

TSA’s 3-1-1 liquids rule applies to wine like any other drink. Liquids in a carry-on must be in travel-sized containers of 3.4 ounces (100 milliliters) or less per item, and they must fit in a quart-sized bag. TSA says anything in a larger container goes in checked baggage. Its alcohol page adds that mini bottles must fit comfortably in that single quart-sized bag.

A standard bottle is 750 ml, so it can’t go through security in a carry-on. Our wine bottle sizes guide lists the smaller formats; even a half bottle is far over the limit. TSA also notes that the final decision rests with the officer at the checkpoint.

Wine bought after security is a different case, since the liquids rule is enforced at the checkpoint and shops in the departure area sell beyond it. TSA’s alcohol page still tells travelers to check with the airline before bringing any alcohol on board.

Important: Carrying a bottle on board doesn’t mean you can open it. TSA and the FAA both state that FAA regulations prohibit passengers from drinking alcohol on board unless it is served by the airline, and TSA adds that flight attendants may not serve a passenger who is intoxicated.

Wine in checked luggage

This is the easy part. TSA says alcoholic beverages with 24% alcohol or less are not subject to limitations in checked bags. Most table wine has about 12% to 15% alcohol, using the Wine Folly ranges in our alcohol guide, and even Port, at 19% to 22% according to Portugal’s Port and Douro Wines Institute, sits below the line (see our guide to wine alcohol content). For wine, the practical limits are your airline’s rules on the number and weight of bags.

The stricter rules are for spirits. The FAA’s PackSafe page says drinks with more than 24% and up to 70% alcohol (up to 140 proof) are limited to 5 liters (1.3 gallons) per packaging and 5 liters in total per passenger, and must be in unopened retail packaging. The FAA points to the regulation behind it, 49 CFR 175.10(a)(4), and notes that in carry-on bags these drinks are still held to 3.4-ounce containers at the TSA checkpoint. Drinks over 70%, such as grain alcohol and 151-proof rum, fall outside it; the FAA lists them separately.

Duty-free wine on international flights

TSA allows one exception to the 3.4-ounce rule for duty-free liquids on international trips. You may carry larger duty-free bottles through a TSA checkpoint if all of these apply:

• you bought them internationally and are traveling to the US on a connecting flight;
• the retailer packed them in a transparent, secure, tamper-evident bag, and the bag shows no sign of tampering;
• you have the original receipt, and the purchase was made within 48 hours.

The bottles still have to be screened, and TSA recommends packing duty-free liquids in your checked bag at your connection anyway, even when they are sealed. In our view, that is the safer choice: if the seal is broken or the receipt is missing, the bottle won’t get through.

Bringing wine home from abroad: US customs

US Customs and Border Protection (CBP) rules apply when you land, whatever you packed the bottle in. A few points from CBP and the federal regulation, 19 CFR 148.33:

• Declare it. CBP says all travelers must complete the CBP Declaration Form 6059B listing purchased goods. If you don’t declare something that should have been declared, you risk forfeiting it; if in doubt, declare it.
• One liter of alcohol counts toward your exemption. A returning resident can include no more than 1 liter of alcoholic beverages in their duty-free personal exemption, and none at all under age 21. That is a little more than one 750 ml bottle.
• Higher limits from some places. Travelers returning directly from a beneficiary country, as defined in the US tariff rules, may include up to 2 liters, if at least 1 liter was produced in such a country. From American Samoa, Guam, the Northern Mariana Islands or the US Virgin Islands, the limit is up to 5 liters, with conditions on where the bottles were bought and produced.
• Duty-free shops don’t mean duty free. CBP says goods bought in a duty-free shop are not automatically free of duty when you return, and that only very limited amounts of alcohol can be included in your exemption. The overall exemption is $200, $800 or $1,600, depending on the countries you visited, and generally requires a stay abroad of at least 48 hours.
• Bringing more. Alcohol beyond your exemption may cost you duty: CBP says that, if warranted, the officer will calculate the duties you owe on goods you bought abroad.
• State law applies too. CBP says the laws of the state where you first arrive in the US govern how much alcohol you may bring and whether you need a license, and it advises contacting that state’s alcoholic beverage control board before you travel.

Note: Leaving the US, your destination country’s customs rules apply. In our view, check that country’s official customs site before you buy a case at the winery.

What airlines say

Airline rules sit on top of TSA and FAA rules, and they change, so check your carrier before you fly. One example, from the airline’s own Wine Flies Free page as we checked it on October 29, 2026 (the page shows no date of its own): Alaska Airlines says “wine flies for free on flights departing from our 34 airports in Washington, Oregon, Idaho, or California to any Alaska Airlines city in the United States.” The program is for Atmos Rewards members, who must be 21 or older and add their member number to the reservation so that their first case of wine doesn’t count toward the checked bag allowance. Alaska considers one case to be “a single box or case containing up to 12 bottles and weighing 50 lbs or less,” and says the wine “must be packed and sealed for transport in a protective shipping container.” Flying from a city that isn’t on the list, all luggage pays standard checked bag fees.

In our view, programs like this make it cheaper to bring wine home from a trip to Walla Walla, or to Paso Robles via San Luis Obispo, both on Alaska’s list; our Paso Robles wine tasting guide is a good place to start planning.

How to pack wine in a suitcase

Nobody can promise a bottle won’t break, but a few habits help:

1. Use a bottle protector or a shipping box. Padded or inflatable bottle sleeves fit in a suitcase; for a case, a styrofoam wine shipper or a box with cardboard dividers is sturdier. Alaska suggests a case or box with styrofoam, cardboard liners or bubble wrap. Our best wine bag guide includes an inflatable travel protector.
2. Put bottles in the middle of the suitcase, surrounded by soft clothes, away from the edges and wheels.
3. Seal each bottle in a plastic bag so a leak doesn’t ruin your clothes. In our view, this is the cheapest insurance there is.
4. Expect an inspection. Alaska notes that TSA may open your container to check the contents, and will reseal it afterward.
5. Watch the weight. Wine is heavy; a full case can approach Alaska’s 50-pound case limit, and most airlines charge for overweight bags.

Bottom line

For domestic flights, pack wine in your checked bag, wrapped well, and you won’t run into TSA limits. For carry-ons, it’s 3.4 ounces or a duty-free purchase. Coming home from abroad, declare everything: the first liter can count toward your duty-free exemption, beyond that you may pay a little duty, and your arrival state’s rules apply. And whatever is in your bag stays closed until you land.
