Aeroplane cabins are maintained at lower pressure, with dry, recirculated air—conditions that accelerate fluid loss. Cabin humidity can drop as low as 5–10%, making it even drier than some deserts. This dryness pulls moisture from your skin and respiratory system, while prolonged sitting causes fluid to pool in the legs. Combined, these factors often leave travellers feeling dehydrated, which can contribute to fatigue, headaches, and muscle cramps.

Good Flyte combines a precise balance of electrolytes and nutrients that help your body absorb and retain water more effectively, reducing fatigue and dryness, and may help reduce jet lag symptoms while you travel, allowing you to arrive ready to take on your destination.

While drinking water is crucial, it’s sometimes insufficient to maintain proper hydration on its own. Electrolytes—minerals like sodium, potassium, and magnesium—are essential for transporting water into cells, ensuring your body effectively utilises the fluids you consume. Without the right balance of electrolytes, much of the water you drink may simply pass through your system without being fully absorbed. This becomes particularly important during flights when dehydration risks are higher and your body’s hydration needs are increased.

Electrolytes like sodium, potassium, and magnesium help your body hold on to water, maintain energy, and keep your muscles and nerves working properly. See more information on our science page.

At Good Flyte, we’ve partnered with aviation and medical experts to develop a hydration and wellbeing supplement specifically designed to address the challenges of air travel. Our formula delivers the optimal balance of electrolytes and vitamins to help your body retain fluids, prevent dehydration, and support overall performance. With our personalised hydration calculator, you can create a tailored plan based on your weight, height, flight duration, aircraft type, and expected cruising altitude. This customised approach ensures that you stay properly hydrated from take-off to touchdown, reducing the effects of jet lag and helping you arrive at your destination feeling refreshed and ready to go.

At Good Flyte, we’ve developed a product specifically tailored to the unique conditions of air travel. Our formula doesn’t overload you with unnecessary sodium or minerals designed for intense physical exertion, typically found in sports electrolytes. Instead, it delivers balanced electrolytes and targeted vitamins in doses aligned with the steady, continuous fluid loss experienced during flights.

Rather than taking large quantities all at once, we recommend consuming Good Flyte in smaller, regular doses throughout your journey. This approach helps your body gently maintain optimal hydration levels without straining or overwhelming your body.

To ensure you get precisely what your body needs, we’ve created a personalised fluid-loss calculator. By considering your body size, flight duration, cruising altitude, and even aircraft type, we help you customise your supplementation to arrive refreshed, energised, and ready to go.
