Yes, you can fly with a 750 ml bottle of alcohol, but in 2026, it must be packed in your checked luggage. Under the global "3-1-1" liquids rule for carry-on bags, you are only permitted to carry liquids in containers of 100 ml or less. A standard 750 ml bottle far exceeds this limit and will be confiscated at the security checkpoint if found in your hand luggage. When packing it in your checked bag, ensure the alcohol content is between 24% and 70% ABV; anything over 70% (140 proof) is considered a hazardous material and is strictly prohibited. For safety, wrap the bottle in bubble wrap or nestle it deep within your clothing to prevent breakage during transit. The only exception for hand luggage is if you purchase the alcohol at a Duty-Free shop after passing through security, in which case it must be carried in a secure, tamper-evident bag (STEB) provided by the retailer.
