Experts reveal common flight food and drink mistakes travelers should avoid

At thirty thousand feet, the human body enters an environment it was never designed for — pressurized, desiccated, and rhythmically disorienting. Yet most travelers surrender their choices to the airline cart, accepting whatever is offered as though the cabin were simply a restaurant with a view. Dietitians and fitness coaches who study frequent flyers have found that the gap between arriving depleted and arriving ready is not a matter of luck, but of intention — small decisions made before boarding that honor the body's actual needs rather than the flight's artificial rhythms.
