Japan Airlines Co., which began Boston services Sunday with its new Boeing Co. 787, may also use the fuel-efficient plane on routes to Spain and Germany as it bolsters services to smaller cities.

The airline is considering flights to Madrid, Berlin and Dusseldorf, which are hubs for partners Iberia Lineas Aereas de Espana SA and Air Berlin Plc, Kiyoto Morioka, vice president, network planning, said in an interview Friday at the company's Tokyo headquarters. The planes may also be used to boost services to New York and London, he said.

Japan Air received its first two 787s last month and two more will arrive "very soon," Morioka said. The carrier, the second to use the plane after All Nippon Airways Co., has ordered a total of 45 Dreamliners to help increase international capacity by 25 percent over the next five years.
