Due to limited capacity at Beijing Capital International Airport, plans were set forth for the construction of a new airport in Daxing. The project was given final approval on 13 January 2013. Construction began in late 2014 and was completed in 2019. The new airport will serve as a hub for SkyTeam alliance airlines (except China Eastern Airlines), while Star Alliance members will stay at Beijing Capital International Airport. Hainan Airlines, which accounted for 10% of Beijing Capital International's passenger seat capacity in 2016, but is not part of any major alliance, will stay at the existing capital airport.
