LPT: Bring and empty water bottle to the airport, fill it up after getting through security. Throw an empty (lightweight, reusable) one in your carry-on. Fill it up after going through security. Saves some money and more airports are putting in the water fountains that have the built-in bottle filler. Plus wherever your destination is, you've got a water bottle you can bring with you.
