Answer 1

In addition to your close proximity to potentially ill people for long periods, plus potentially touching dirty surfaces, there are 3 other risky contexts to flying – the crowded areas at security, takeoff, and the period after landing. Many airlines run the ventilation while the plane is on the ground, but the FAA does not require them to do so. How the ventilation is run varies slightly from carrier to carrier.
