I just scanned the list and noticed the verboten liquids. No longer are liquids permitted on most flights. You'll be asked to throw it away or drink it on the spot. Empty bottles, however, are not a problem. What I have done is to take an empty water bottle, then filled it at an airport drinking fountain while waiting for the flight.

Most flights offer in-flight beverage service but there is still much discussion about the safety of beverages made with water and/or ice from the bacterial-laden holding tanks of planes. Carrying one's own water is one alternative.
