Yup.

I absolutely might.

I just read that the the worst thing you can do on an airplane, according to a recent survey, is sneeze and cough -- i.e. have obvious cold symptoms -- and not wear a mask.

That's probably true at a concert and a lecture too.

Being out of the habit of masking isn't a great excuse. And everybody has trouble breathing with a mask on. But you can adjust.

That being said, I flew (masked) from California to Philadelphia knowing I had Covid.

So I'm in no position to judge you.
