While it is illegal to consume your own alcohol on a plane, you can bring small bottles of alcohol on board with you. The Transportation Security Administration (TSA) governs air travel in the US and has set out guidelines for carrying alcohol on planes. Alcoholic beverages with more than 24% but not more than 70% ABV are limited to 5 litres per passenger in checked bags and must be in unopened retail packaging. Alcohol under 24% ABV is not subject to these limitations. For carry-on luggage, the same 3-1-1 rule that applies to toiletries also applies to liquor, meaning passengers can pack small bottles of alcohol (less than 3.4oz) in a clear, quart-sized bag.

What You'll Learn

Alcohol volume and quantity restrictions
Alcohol in Checked Luggage:
For alcoholic beverages with an alcohol content of more than 24% but not exceeding 70% ABV (48-140 proof), there is a limit of 5 liters (1.3 gallons) per passenger. These beverages must be in their original, unopened retail packaging. Alcoholic beverages with 24% ABV or less are not subject to quantity limitations in checked luggage.
Alcohol in Carry-On Bags:
The rules for carrying alcohol in your carry-on bag are more stringent. The Transportation Security Administration (TSA) in the US allows passengers to carry mini bottles of alcohol in their carry-on luggage, as long as they meet certain criteria. Each bottle must contain 3.4 ounces (100 ml) or less of alcohol. These bottles must fit comfortably into a single quart-sized, clear zip-lock bag. It is important to note that the final decision on whether your alcohol will be allowed through the checkpoint rests with the TSA officer on duty.
Drinking Alcohol on the Plane:
While you can bring your own alcohol on board, drinking it on the plane is prohibited by the Federal Aviation Administration (FAA). Passengers who do not comply with this regulation may face hefty fines. Therefore, it is best to refrain from consuming your own alcohol during the flight and instead purchase in-flight beverages if you wish to drink alcohol.
To ensure a smooth travel experience, it is recommended that you carefully review the TSA guidelines, airline regulations, and customs rules before packing alcohol in your luggage or carry-on bag. Additionally, consider investing in travel accessories designed for safe alcohol transport, such as silicone-wrapped glass bottles and bubble chamber packs to prevent breakage.

Carry-on allowances
Alcohol is permitted in carry-on luggage, but there are strict rules to follow. Alcoholic beverages with more than 24% ABV but no more than 70% ABV (140 proof) are limited to 5 litres per passenger in checked bags and must be in unopened retail packaging. Alcohol under 24% ABV is not subject to limitations in checked bags.
For carry-on luggage, the rules are more stringent. Alcohol is only permitted in containers up to 3.4 ounces (100ml) in volume. This means only mini bottles will be allowed through security. These bottles must be placed in a quart-sized (1 litre) clear, zip-lock bag, and the bottles must fit "comfortably" inside. The final decision on whether the alcohol will be allowed through security is made by the TSA officer on duty.
It is important to note that drinking your own alcohol on a commercial flight is prohibited and can result in fines. Alcohol purchased at duty-free can be consumed on the plane but must be packed in a transparent, tamper-evident bag, and the receipt must be kept.

Checked baggage rules
Alcoholic beverages with an alcohol content of more than 24% but not exceeding 70% ABV (48-140 proof) are limited to 5 litres (1.3 gallons) per passenger in checked bags and must be in unopened retail packaging. Alcoholic beverages containing 24% ABV or less are not subject to quantity restrictions in checked bags.
When packing alcohol in checked luggage, it is important to take precautions to prevent breakage. Wrapping clothing, such as scarves or sweaters, around the bottles can help cushion them and prevent clanking during transport. Additionally, consider using bubble chamber packs, which are inflatable containers that surround bottles with air, providing extra protection.
It is worth noting that individual airlines may have their own restrictions in addition to the baseline rules set by the TSA. Therefore, it is recommended to check with the specific airline for any further guidelines or limitations regarding the transportation of alcoholic beverages in checked baggage.
Furthermore, travellers should be aware that consuming alcohol on board an aircraft is prohibited unless served by a flight attendant. It is also important to ensure that any alcohol purchased at duty-free shops is packed in a transparent, tamper-evident bag, and that the receipt is kept as proof of purchase within the last 48 hours.

Drinking on board
If you're bringing alcohol on a plane, there are a few things to keep in mind. Firstly, alcoholic beverages with more than 24% but not more than 70% ABV are limited in checked bags to 5 litres per passenger and must be in unopened retail packaging. Alcoholic beverages with 24% ABV or less are not subject to limitations in checked bags.
When it comes to carry-on bags, alcohol is permitted as long as it is under 70% ABV and the container is less than 3.4 ounces. These mini bottles must be able to fit comfortably into a single quart-sized bag. It's important to note that the final decision rests with the TSA officer on whether alcohol is allowed through the checkpoint.

Packaging and sealing requirements
The Transportation Security Administration (TSA) in the US governs air travel and sets the baseline rules for carrying alcohol on a plane. Alcohol under 70% ABV (140 proof) is allowed in carry-on bags, provided the container is less than 3.4 ounces (100ml). This means that 1-ounce bottles of alcohol are allowed in carry-on luggage. The TSA states that mini bottles of alcohol in carry-on luggage "must be able to comfortably fit into a single quart-sized bag". This is in line with the standard 3-1-1 rule that applies to toiletries. The final decision on whether an item is allowed through the checkpoint rests with the TSA officer.
To ensure your alcohol is not confiscated, it should be in its original, unopened packaging. This means that if you are packing mini bottles, they should be in their original, unopened packaging and comfortably fit into a single quart-sized bag. If you are packing larger bottles, they should be unopened and you should take care to prevent breakage. This can be done by wrapping clothing around the bottles to keep them from clanking into one another during transport. Bubble chamber packs are also a great solution, as these inflatable containers surround your bottles with air to keep them from breaking.
For alcohol purchased at Duty-Free, ensure the bottles are packed in a transparent, tamper-evident bag, and keep the receipt to prove it was purchased within the last 48 hours.
There are no limitations for alcohol under 24% ABV (48 proof) in checked luggage. For alcohol between 24-70% ABV (48-140 proof), there is a five-liter maximum per passenger, and the liquor must be stored in unopened retail packaging. This means that you can pack several 750ml bottles and still have room to spare.
