[*] Yes I'm prioritizing my comfort over safety for others, but that's the American Way (tm), isn't it.
(I switch to a mask with no metal in it for airport metal detectors, but I can switch back again immediately afterwards.)
It's actually quite poor and significantly worse than most indoor spaces I've entered (most spaces aren't great at around 800-1600ppm). On planes I've measured※ very high CO2 levels (1800-4000ppm), with the worst air during boarding and deplaning. This matches the findings of others (both amateur and professional researchers).

(I don't see an issue with wearing an exhalation vent next to folks who aren't wearing masks themselves. If they cared about the air they'd also be wearing a mask. If I sat next to someone wearing one I'd switch back to the 9205+.)
Are we expecting almost all the clean air to be from outside, minimal amounts from recirculation?

I'd have expected a better mix (more fresh air) since even with filtration removing many particulates and viruses, high CO2 levels still cause worse cognitive performance.
Put a lot of people in close proximity for a long time and it's going to be very hard to prevent transmission of airborne viruses...
Based on Veritasium's recent video, given the cabins are pressurized by bleeding air off of the jet engine might not be too surprising about CO2 or particulates. However the cabin air is also exceptionally dry.
