I have a flight in late December booked on that route.

It hasn't been cancelled but it seems they have stopped selling seats - likely because it's scheduled to be operated by a 737 Max aircraft.

Right now, I have asked my agent to look at options as I am betting that Max takes longer than this to come back into service.

If the Max comes back into service quickly, this may mean some seat sales! If it doesn't, expect a very tight market over the holidays.
