In 2026, the best drinks to order on a plane are those that remain flavorful despite the low humidity and cabin pressure. Tomato Juice or a Bloody Mary mix is the top recommendation; the "savory" (umami) profile of tomato juice is actually enhanced in the air, whereas sweet and salty flavors are dampened. For a refreshing non-alcoholic choice, Ginger Ale is a classic for its ability to settle the stomach and its crisp, zesty finish. If you're looking for an alcoholic cocktail, a Gin & Tonic is often the best "safe bet" because it only has two ingredients and is hard to get wrong. Many travelers also opt for herbal teas (like peppermint or chamomile) to stay hydrated and relaxed without the diuretic effects of caffeine. For pure hydration, plain water remains the gold standard, ideally without ice to avoid potential bacteria from the plane's water tanks. Avoid heavy coffee or sugary sodas, which can lead to "crashes" and dehydration during long-haul flights.
