"Not to be too graphic, but if I drink enough water to stave off thirst on a long flight I have to stop too often or use a 'receptacle' in the airplane, which isn't easy. Do the pros fly thirsty or do they know something I don’t?" — William P.
“Pilots have invented about as many ways to balance fluid intake versus outflow as they have methods to hot-start an engine. Here’s my solution, proven on many long-distance flights: Grapes.
I wash and chill clusters of grapes (green or red, your choice, but definitely seedless) and keep them handy in a small cooler or insulated bag. They’re mostly water, so snacking on them helps you feel less thirsty without gulping liquids. Grapes also are a low-calorie, low-salt, satisfying snack that doesn’t leave crumbs in the cockpit.
Other mostly-water fruits, like oranges, also can work, but they all require peeling and handling that can get sticky. Grapes come in tidy, ready-to-eat, single-serve clusters.
Next time you plan a long leg, bring a bunch of grapes and see if they improve your endurance.”
