I thought this was interesting data. I had my Aranet CO2 monitor with me. I saw the same data on other flights. Planes seem to be bad until they get under their own power (and presumably turn on the AC). Tour-style buses are bad. Metro rail seems ok!

Caveats: I’m not sure how correlated low CO2 levels are with low covid levels. The Aranet was in my backpack. I’m not a scientist.
