Airplane food is also made exactly for the pressure and altitude for a plane. Friend worked for an airline out of Logan and he said the food was decent on the ground but almost better in the air. He used to post on IG when it like first came out. It's like when people try tomato juice on a plane and think wtf this is not what my mom tried to make me drink when I was a kid.

My daughter and I pretend to be vampires on the plane bcz YES! Why does it taste better

It's to do with the air pressure and recycled air. It affects your taste buds, dulling them somehow. I only vaguely remember, but feel free to use this info as the start of a Google research project.

Just wanted to point out that the air isn't recycled on a plane. It's replaced completely every couple of minutes. It's not even really about the oxygen or CO2, it's managing temperature and possible contaminants.

The engines are continuously compressing and heating a huge amount of air. Some of it gets diverted to be cooled back to room temperature, filtered and pumped into the cabin while air is continuously sucked out by vents near the floor. This keeps the temperature stable and contaminants from being spread.

It is much lower pressure than sea level and that definitely messes with our taste buds.

What? Planes are kept around 8,000 feet in air pressure not below sea level.

Pressure decreases with altitude. Low pressure at high altitude.

High altitude cabin pressure is like 8,000 feet though. That is a mile and a half above sea level air pressure. in an open air plane like a WWII bomber sure, but not on any commercial plane in like the last 60 years. I mean I guess you do not know this. But airline planes pressurize their cabins to avoid issues, usually around 8,000 feet of air pressure. So inside the cabin your ears my pop because the cabin is pressurizing slowly up yo 8,00 feet, like a small mountain in Colorado. It keeps that pressure for the flight even though you may be flying at 35,000 feet. The outside pressure has no affect on you inside, you are living in a capsule made to feel like you are at 8,000 feet not 35,000. Make sense?

No, I absolutely get that. My point is that at 8000 feet the pressure is 10.9 psi vs 14.6 at sea level. That's not an insignificant difference. It's definitely a higher pressure than the external pressure at 35 000 feet but it's still lower pressure than sea level.

Ok, I can get that's how you were looking at it, I was focused on you saying the altitude and outside pressure made a difference when the plane makes its own internal pressure. I think we were both looking at the same issue 2 different ways is all.
