Chengdu Shuangliu International Airport (CTU/ZUUU) is one of China's busiest airports, serving as the primary aviation hub for Sichuan Province and the broader southwest region. Located in the Shuangliu District approximately 16 kilometers from central Chengdu, it handles tens of millions of passengers annually and serves as a major connecting point between inland China and international destinations. The airport operates two passenger terminals and serves as a hub for Sichuan Airlines and a focus city for Air China. It handles a wide range of domestic and international routes, connecting Chengdu to destinations across Asia, Europe, North America, and beyond. The airport has played a key role in supporting Chengdu's growth as a major economic and cultural center. Chengdu Tianfu International Airport, which opened in 2021, now serves as an additional gateway for the city, with Shuangliu continuing to operate significant traffic. The two airports together form a dual-airport system for the Chengdu metropolitan area.
