2. Take An Empty Water Bottle Through Security
The people working security at airports get real persnickety when you try to carry a bottle of water through an airport, but that doesn’t mean you can’t bring an empty vessel through the checkpoint and then fill it up at a water fountain once you’re on the other side. Don’t feel like bringing an empty bottle? Buy a bottle of H2O at a convenience store near your departure gate, because whatever you do, don’t drink the airplane water (more on that in a second).
