Would advise against that now and a month from now. Under the current circumstances it is unlikely 9W will be flying in Dec 19. It doesn't seem likely they will be able to turn around.
The problem with booking this flight makes you committed to this ticket. That means when your 9W flight gets cancelled (which may be a month or a few months for now) prices may have gone up quite a lot. That's the risk you're taking.
