Here’s Why Food Tastes Different While Flying on a Airplane

By /

Travelers often notice a different taste in the foods and drinks they consume once their airplane takes off.

Key Facts:

• Low cabin humidity and pressurization reduce moisture in the body, affecting taste buds.
• Noise and vibration at high altitudes also influence how flavors are experienced.
• Certain tastes like sweetness and saltiness seem weaker, while spices and sour notes stand out more.
• Tomato juice and ginger ale are popular inflight choices because they taste stronger in the air.

The Rest of The Story:

Scientists say that humidity levels on airplanes are much lower than those on the ground, causing dehydration. This dryness affects nasal passages and makes food seem bland.

Cabin pressure also changes how flavors register on the tongue, with sweet and salty tastes muted more than sour and spicy ones.

For these reasons, dishes with extra seasoning or stronger flavors may seem more appealing in flight.

Beverages like tomato juice and ginger ale benefit from that altered perception.

Tomato juice has umami qualities that stand up to thinner, pressurized air.

Ginger ale often feels both refreshing and more flavorful.

Meanwhile, coffee can be hit or miss; some airlines offer espresso on select routes, but passengers often note that standard airplane coffee can fall flat.

Flight noise and vibrations can diminish a person’s sense of smell, further altering flavor.

This helps explain why some folks enjoy foods on planes that they rarely crave on the ground.

It is also one reason airlines may serve strongly seasoned meals, including pasta, which many travelers report tasting better at high altitude.

Experts caution that ordering too many alcoholic beverages can worsen dehydration, making it harder to enjoy meals and stay comfortable.

The Bottom Line:

Airline meals taste different for scientific reasons related to cabin pressure, low humidity, and noise.

Flavor profiles shift at 30,000 feet, which is why many people reach for ginger ale or find tomato-based drinks more appealing.
