Why Do I Get Sick on Airplanes? How to Prevent Getting Sick on an Airplane (2026 Guide)

Fourteen years ago, at 19, I began my journey with what would become Pre Flite while managing over 200 employees at Portillo’s in Chicago. I worked 15-hour days and couldn’t afford to get sick. That’s when I created my first “hydration cocktail.”

Why Do I Get Sick on Airplanes?

Airplane cabins have very low humidity, which dries out your mucous membranes and makes it easier for germs to enter. Air is recirculated, pressure changes affect your sinuses, and travel stress weakens your immune system. Add jet lag and disrupted routines, and it’s no wonder so many people get sick after flying.

How to Prevent Getting Sick on an Airplane

  • Start hydrating before you board.
  • Support your immune system with key vitamins and minerals.
  • Protect your gut with prebiotics.
  • Move around when possible, use nasal saline, and avoid alcohol and caffeine.

My Personal Solution: Pre Flite

After years of mixing separate products with too much sugar and ingredients that didn’t always aid my health, I formulated Pre Flite: a single convenient packet with everything I needed for travel. It kept me healthy through Navy deployments, long ultra races, high-altitude treks in Nepal, and countless flights all over the world.

Why It Works for Everyday Travelers

Whether you’re flying for work, family, or adventure, Pre Flite delivers hydration, immune support, and recovery in one easy step.
