All Nippon Airways Co. plans to slash costs by ¥100 billion and expand international flights as it gears up for rising competition at home.

The carrier, the world's only operator so far of Boeing Co.'s 787 Dreamliner, plans to boost international capacity by 22 percent in the two years starting April 1, the carrier said Friday.

The cost savings are planned by the end of March 31, 2015, it said.
