Overview

• Veteran flight attendant Sue Fogwell says the very high sodium content in Bloody Mary mixes can accelerate fluid loss during extended flights.
• Reduced cabin pressure alters taste by dampening sweetness and boosting umami, making tomato juice more appealing but not more hydrating.
• Crew members caution against drinking tap water from aircraft tanks and recommend avoiding coffee or tea made from it.
• The NHS advises passengers to sip clear fluids like bottled water and to limit alcohol and caffeine intake to combat cabin-induced dryness.
• A Cornell University study found that in-flight noise amplifies umami flavors, reinforcing savory drink preferences at altitude.
