No, planes have the best ventilation systems of any indoor setting.

Amazingly effective. Maybe one of the best places to quarantine due to fast air change rates, as long as it is in the air.

Yes. They have to since the air must be ventilated.

Yes, and they've drastically improved the filters ever since Covid came out so they're much better today then they were in 2020!

FWIW

and there probably aren't any viable viruses in the air at 40,000 feet. Certainly not after they've passed through the compressor blades on the jet engines to be brought to fairly high pressure in a few milliseconds, adiabatic compression heating will churn out air that went from -55C at maybe 100 millibar to about +90C at 1 bar. Then that hot high pressure air has to pass through some external heat exchangers to chill it back down before it's sent into the cabin through expansion valves to match interior pressure of about 0.75 bar. That is gonna sterilize the air, which then will quickly be swept back overboard via the vents after it picks up whatever people cough or sneeze into it.

Yes, and those temperatures would kill off most bacteria or what ever other form of a virus too.

Shortly after Covid was discovered early in 2020, the Japanese government worked with the airlines to get a quick boost in funds to produce a much more sterile and smaller filtration fabric for all of the filters in their aircraft. Several other Asian countries also bought those filters from Japan too. Not sure whether the US did or not though.

FWIW
