Ok good to know, just don't sit near anyone else and you're covered
Well, this really takes the cake for conspiracy theories:

That's both too coherent, and doesn't make enough sense to be a real conspiracy theory.
Sure, as long as everyone is kept separated, and aren't sitting inches/centimeters away from each other. It works like smoking and non-smoking areas; those planes will be loaded with the plague for a decade after sick people quit being there.
It means that you're at risk only if the couple persons you may be sitting next to are infectious, or if the person that's been using your seat in the past day or so was. This is about as much risk as you take when using any form of public transportation and many public spaces. The air being recirculated doesn't add to that.
I haven't flown much in the last 19 years for some reason (the reason is that it's hell), but I remember the air circulation being a nozzle that may or may not work, and if it works, at maximum, will stop about half of your forehead from sweating or freezing, depending on the temperature in the plane. Unless everyone else was also trying to use the air circulation, and everyone got a negligible amount of air. Again, this is the US, so being absolute shit is expected.
Also, the asshole behind you will never stop coughing on you.
And if the hospital is packed with vulnerable people and they can't treat you for, say, a car accident, you're in as much deep shit as if you were actually having serious trouble with the virus.
Yeah, you're bleeding out at the hospital, but free coronavirus while your family waits is
something.
