This was cute. Under Food and Drink, it specifies that you may bring:
Beverages brought from home or purchased before reaching the security checkpoint in a 3 oz. or smaller container and in your quart-size, zip-top plastic bag.I realize they're saying this to be consistent with their three-ounce rule. But I still chuckle when I think of somebody bringing a three-ounce container of soda. You know, in case they get thirsty.
