The major airports (PEK, CAN, etc.) in Mainland China only operates 1-2 flights to Taipei tomorrow. But they don't seem to be cancelled just yet.What about flights between other Chinese cities and Taiwan? Like Hong Kong-Taipei, which are one of the more popular routes, for example.
Other mainland airports don't fly to Taipei (I think) due to covid.
That being said, HKG-TPE seems normal, around 10 planned, not much cancellations.
