Most of us underestimate how much water we should consume on a daily basis, but we should not overlook it on the day of a flight!

Water works wonders when it comes to off-setting jet lag. It hydrates and promotes mental clarity. It also helps with fatigue, dizziness and lightheadedness, all common symptoms when we fly.

The best part is: water is free when you're on board, and you can order as much as you need.

Pro tip: purchase a bottle after you've arrived at your gate, and you won't have to ask for water on the flight.
