All kidding aside, I failed to mention one very important thing - keep water handy. We carry an old chinese food container with a lid, but any small dish will due. (You can't leave water in it, the lid is just to keep it covered so it stays clean and the water left inside once you dump it doesn't get on everything else in your carry on.) We use this dish in the airport terminal and on the plane. Buy a bottle of water on the plane and pour some in his travel bowl during the flight. If you're thirsty, he/she probably is too!
