Yeah, unless that vaccine everyone is working on _really, really_ works I don't see demand for airplanes (or other forms of public transportation, for that matter) coming back to anywhere near the level it was before C19. FWIW, whatever travel I do this year will be by car.

And chances of that vaccine working _reliably_ are pretty slim: we do not have vaccines for any other coronaviruses, and they mutate. Our vaccines against the flu (which is not a coronavirus, but which also mutates) leave a lot to be desired.
