Question: are bottles of wine allowed on a plane?
Answer: Like all liquids, it's subject to the TSA's 3-1-1 rule for carry-ons, which means you can't pack bottles that are larger than 3.4 ounces, plus they must all fit into a single 1-quart bag. The only way to bring a full bottle of wine into the cabin of a plane is to buy it after you clear airport security.
