Dalian Jinzhouwan International Airport (IATA: DLC, ICAO: ZYTL) is an international airport being built to serve the city of Dalian in Northeast China's Liaoning province. Once open, it will replace the existing Dalian Zhoushuizi International Airport as the city's main airport. It is being built on a 21 square kilometres (8.1 sq mi) of reclaimed land off the coast of Dalian. Expected to be open by 2025, it is set to become the world's largest offshore airport.
