No, you cannot put a standard-sized bottle of wine in your carry-on luggage due to the TSA’s 3-1-1 liquids rule, which limits liquids to containers of 3.4 ounces (100ml) or less. Since a standard wine bottle is 750ml, it far exceeds this limit and will be confiscated at the security checkpoint. The only exception is if you purchase the wine after the security checkpoint at a duty-free shop or an airport terminal retailer; in this case, you can carry it onto the plane. For international travelers with a connection, duty-free wine must be placed in a "Secure Tamper-Evident Bag" (STEB) with the receipt visible. If you want to bring wine from home, it must be packed securely in your checked luggage. To prevent breakage, use specialized "wine wings" or bubble-wrap sleeves. There is no limit on the amount of wine (under 24% alcohol) you can put in checked bags for domestic US flights, though international arrivals must stay within their customs duty-free allowance to avoid taxes.
