Start to acquaint your body with your new time zone by eating meals based on the time at your destination. Everytime I fly to Asia, the airline tries to serve me breakfast right before we land at 6pm--I’m not into that! Get your body used to your new mealtimes asap by eating the breakfast food or lunch/dinner food you brought along at the proper time.
Don’t forget to keep Hydrating! A fun tip for you: Flight attendants will usually fill your reusable bottle so you don’t have to go through a bunch of plastic cups or bottles.
If you’re planning to sleep on the plane, make sure to have these essential items: Eye mask, noise canceling headphones or ear plugs, an extra pair of socks, and a cozy hooded sweatshirt.
Airplanes are unfortunately full of germs with all those strangers in close proximity! Make sure you are washing your hands thoroughly and regularly. Make it a reason to get up and stretch your legs.
