Dandong Langtou International Airport (IATA: DDG, ICAO: ZYDD) serves Dandong, a city in Liaoning Province, northeastern China, situated on the Yalu River bordering North Korea. The airport provides essential air connectivity for a region that is otherwise geographically remote from major Chinese aviation hubs. The airport handles a modest volume of domestic traffic, with routes primarily connecting Dandong to major Chinese cities such as Beijing, Shanghai, and Guangzhou. Its international designation reflects its potential for cross-border routes, though scheduled international services have historically been limited. Dandong itself is notable as a key trade and logistics point between China and North Korea, and the airport plays a supporting role in the region's broader economic and tourism activities, including visitors drawn to the famous Broken Bridge and Yalu River scenery.
