Hainan Airlines will become the second Asian airline to use one of Boeing's 787 Dreamliners on a route from Sea-Tac Airport beginning in January.
The Chinese airline has been using Airbus A330s on the route. Hainan follows Japan's All Nippon Airways in flying a Dreamliner on a route from Sea-Tac.
United Airlines had been scheduled to use a Dreamliner on its Sea-Tac-to-Tokyo route, but the airline is cancelling its Tokyo route from Sea-Tac next month in the face of competition from Delta Air Lines and ANA.
The first flight of Hainan's Dreamliner from Sea-Tac to Beijing is scheduled for Jan. 10. Those four-times-weekly flights now are scheduled to continue through the end of March, but may continue after that date.
The 787 Dreamliner is Boeing's newest plane. Its the first airline with a composite fuselage and wings. The twin-engine plane was designed to serve long routes that don't generate enough traffic for larger aircraft such as the Boeing 777 or 747.
Delta Air Lines competes with Hainan on the Beijing route.
