Taichung International Airport / Ching Chuang Kang Air Base — Taichung (Qingshui), Taiwan

Sharing its runways with a Republic of China Air Force base, RMQ serves Taichung, Taiwan's third-largest city, from a site historically known as Ching Chuan Kang, or CCK, a name still used informally by many residents. The base gained international prominence during the Vietnam War era, when American forces used it as a logistics and refueling hub, and the military connection persists today even as civilian passenger traffic has grown substantially. Taichung itself sits in central Taiwan and has developed into a major manufacturing and cultural center, home to the National Taichung Theater and a thriving arts scene. RMQ primarily handles domestic connections to Taipei, Kaohsiung, and outlying islands, alongside a growing slate of international routes to destinations in China, Japan, and Southeast Asia. Expansion projects in recent years have aimed to relieve pressure on Taiwan's busier northern airports by strengthening central Taiwan's direct air links abroad.
