No, you cannot bring a standard 750ml bottle of wine through airport security in 2026 due to the 3.4 oz (100ml) liquid rule. The only way to have a full-sized bottle of wine in your carry-on is if you purchase it at a Duty-Free shop after passing through security. These bottles must be packed in a transparent, secure, tamper-evident bag (STEB) with the original receipt visible. If you are traveling on a connecting flight, TSA will allow the STEB through as long as it shows no signs of tampering. For wine brought from home, it must be packed in your checked luggage. Note that while you can carry wine, you are legally prohibited from consuming your own alcohol on board the aircraft unless it is served to you by the flight crew.
