China's live-fire drills around Taiwan force reroutes, cancel nearly 900 flights and could affect 100,000 passengers

The drills produced immediate operational disruption: nearly 900 flights impacted, up to 100,000 passengers affected, 36 domestic cancellations to Kinmen and Matsu and multiple transiting flights diverted — a direct hit to airline schedules, revenues and airport operations.

The incident is part of a sustained uptick in PLA activity that alters regional airspace risk and planning; see the recent report on the PLA carrier Fujian's transit and broader imagery showing a rapid expansion of China's military air power (PLA carrier Fujian transit) and (WSJ satellite images show rapid expansion of China’s military air power).

These maneuvers compound existing route and overflight friction in Northeast Asia — earlier diplomatic spats already forced the cancellation of roughly 1,900 China–Japan flights in December, increasing the potential for network disruption and longer routings for carriers operating in the region (cancellation of 1,900 China–Japan flights in December).
