Food tastes different on a plane than it does on the ground. Your taste buds are dulled at altitude. Most planes are pressurized to 8000 feet, while newer generation aircraft like the Boeing 787 and Airbus A350 are pressurized to 6000 feet.
That’s why tomato juice is a surprisingly popular drink on planes (and here I thought it was because tomato juice is an excellent source of vitamin c and vodka).
