The airlines are in bug trouble already.
Your government will send a plane and charge you for it. They did that after hurrican and did it for those in Wuhan China.
Make sure the embassy/consulate knows your contact info if you think the airline might abandon you.
Personally, if you want out I would pay the piper and standby for any flight out.
You dont know if they wont shut the big hubs down for a period of time.
Time to get into John Candy/Steve Martin mode and Planes Trains Automobiles home.
If my employer didnt care Id book a room in 2 week cancellable increments and make a big Carib beer run.
