I've read the air in the airplane itself is much safer to breath (COVID-wise) than the air in airline terminals.
Apparently commercial jets have extremely good filtering, whereas terminals don't.
But obviously to get to the plane we must spend time in the terminals, often these days lots of time.![]()
That is true only while the plane is in flight. At the gate during boarding and after landing, the CO2 levels get shockingly high because air is not circulated the same way as it is in flight.
I carry a CO2 monitor and got this photo of air on a plane while boarding a few weeks ago. CO2 is an indicator of how well ventilated a space is. For reference, outside air is around 400.

During our flight the levels never got to what I would consider to be a low range.
