Yes, you are permitted to pack alcohol in your checked (hold) luggage, but there are strict rules regarding the alcohol by volume (ABV) and the quantity. For beverages with less than 24% ABV (like wine and beer), there are generally no quantity limits from a safety perspective, though you must stay within your airline's weight allowance and your destination's customs duty limits. For spirits with 24% to 70% ABV, most international regulations (including the FAA and TSA) allow up to 5 liters per person. Anything over 70% ABV (140 proof), such as certain high-strength rums or absinthes, is considered a fire hazard and is strictly prohibited in both checked and carry-on bags. To prevent breakage, it is best to use specialized "wine sleeves" or wrap the bottles tightly in thick clothing and place them in the center of your suitcase. Also, be aware that you must declare alcohol at customs upon arrival; if you exceed the "duty-free" allowance (usually 1 liter of spirits or 2 liters of wine), you may have to pay additional taxes.
