Get some little airline liquor bottles or any other bottle less than 3.4oz and fill them up with your beverage of choice and you can carry them on, just have them in a clear 1qt baggie and in a basket when going through security. They are legal because they are under 3.4oz, and you can have more than 1 bottle as long as each is under 3.4oz, that way you can also enjoy a "nip" on the plane.

Here is the rule:
When it comes to bringing liquids or gels aboard an airplane, you are allowed to bring 3-ounce (actually 3.4 ounces or 100 ml) containers filled with the shampoos, liquid soaps, mouthwash or other liquid items of your choice within their carry-on luggage
