Editing Travel (section)

== Preparing for your flight ==

* '''Bring a water bottle''': Fill after security. Cabin humidity is very low (10-20%), causing dehydration. Drink water regularly during the flight. Large (preferably 24oz+).
* '''Have enough electrolytes:''' Eat sodium and potassium rich foods before your flight, on the plane, or during any layover if you have trouble retaining water.
* '''Pack extra medication''': Bring additional doses, and store it in multiple compartments, in case you lose it or extend your trip. Keep in your onboard baggage for easy access.
