Alcohol on Carry on Baggageに関する深掘り記事をまとめてご紹介します。関心のある方は必見です。

If you want to bring a full-size bottle of wine or whiskey as a gift, buy it after security. Seriously. Once you’re past the checkpoint, you can buy a 750 ml bottle from the duty-free shop. They’ll seal it in a special bag with a receipt. You can even open it during the flight—but be careful, because flight attendants might serve you, and you can’t drink your own booze on most airlines. Wait, what? Yes, that’s a thing. Many airlines prohibit passengers from consuming their own alcohol on board. The logic? Liability. If you get drunk on your own secret stash and start dancing in the aisle, the airline gets sued. So keep that bottle sealed until you land.

And please, for the love of turbulence, don’t try to pass off a flask as a “medical device.” It’s not. It’s a flask. TSA agents have a sense of humor, but it runs out fast at 5 AM.

What About Beer? Or Canned Cocktails?

Canned cocktails and beer follow the same rule: 3.4 ounces max per container, all in your quart bag. So no, you can’t bring a six-pack of IPA to Share with the person next to you (unless you plan to drink 100 ml cans). But honestly, who travels with six tiny beers? That’s just weird. Tip: If you’re craving a drink mid-flight, buy one from the cart. It’s pricey, but it’s legal, and you won’t end up on a no-fly list.
