If only we had better air systems to go with these $1,000 tickets , but that's demanding a lot from the makers of 737max and such :p

My less empirical info is that airflow in a plane mostly goes from being input above your head, and exhausted from the pressurized cabin at your feet, meaning you have less exposure to anyone not in your row.
Remember that aircraft pressurization systems were designed to be smoked in, other than the newest designs. They needed enough airflow to not totally choke out passengers on a cross country or cross atlantic trip.
I'm not saying this is the case necessarily for planes, but I'm just trying to provide context for how proxy measures of air quality may not tell the full story.
Most systems lead to a dry throat due to bad filter designs and improper humidity regulation which is a shame.
