The problem with aircraft is that the cabin air is very dry, (bleed air from the engines that has been run through airconditioning packs and is at least partly recycled). This dries out the mucous membranes in the nose, which in turn dulls your sense of smell.

Your sense of taste isn't standalone - it depends heavily on your sense of smell. So with that missing/impaired, food will taste bland or even entirely different to how it does on the ground.

Come to think of it, this may also be a factor in the ISS as well as the congestion problems they have. It would be interesting to know if they have humidifiers on board up there.

::Edit:: Yes they do, sort of! it's the Temperature and Humidity Control (THC) subsystem of the Environmental Control and Life Support System (ECLSS).

Has any airline ever tried a humidifier? Seems too simple to not have thought of.

The corrosion was my thought as well. The other reasons make sense to me as well. And go figure the private flights have figured it out haha.
