I think that we need to know quite a bit more about the virus before we can even think of a timeline right now, not just for flying, but for opening up the economy too.
We need to understand, for instance, the exact incubation period, at what point someone becomes contagious, whether someone who has had it can get it again, whether someone who has it can infect others if they get infected, how fast and whether it mutates (making vaccines and testing a potential challenge) and morbidity rates.

To me the next goal after containment needs to be to not eradicate it (that is a long way off right now), but to get it to the threat level that we currently have with influenza, which most people feel is acceptable (we don't tend to automatically go into stay-at-home for the 'flu).

That means good testing, having treatments that make it less lethal, or less contagious or both, which includes drugs that alleviate the worst symptoms and permanent damage and vaccines.

Until then, being in an elevated (but not super-high) risk category, I am staying at home.
