Kinmen Airport — Shang-I, Taiwan

Kinmen Airport lies on the Kinmen Islands, a Taiwan-administered group set just off the coast of mainland China, far from Taiwan's main island. At an elevation of about 93 feet, it operates a single asphalt runway near 9,843 feet, supporting the busy air link that connects the islands to Taiwan proper across the strait. Given the islands' distinctive geography, close to the mainland yet governed from Taipei, air service is central to daily life and travel for residents and visitors alike. The KNH code identifies this important regional airport, whose flights to Taiwanese cities carry substantial passenger numbers relative to the size of the island group it serves.
