Yes, you can check a box of beer on a plane, provided it is securely packed and falls within the airline's weight and liquid requirements. According to 2026 TSA guidelines, there is no limit to the amount of alcohol under 24% ABV (which includes almost all beers) that you can pack in your checked luggage, as long as it stays within the standard 50 lb (23 kg) weight limit for the bag. However, "checking a box" usually refers to the original cardboard packaging, which is not durable enough for the rough handling of airport baggage systems. To ensure your beer arrives intact, you should place the cans or bottles inside a sturdy, hard-sided suitcase or a specialized heavy-duty shipping box reinforced with plenty of bubble wrap or "bottle protectors." It is a high-value tip to double-bag each bottle in a leak-proof plastic bag to protect your other belongings in case of a rupture. Most airlines will also ask you to sign a "limited liability" waiver for fragile items, meaning they won't compensate you if a bottle breaks, so the responsibility for a "beer-proof" pack job lies entirely with you.
