787 woes have cost largest operator $15.4 million

TOKYO — All Nippon Airways, an enthusiastic Boeing customer now reeling from battery problems on its Dreamliner jets, said Thursday that the grounding of its 787 fleet hurt sales by about $15.4 million in January, casting a shadow on the airline’s future earnings.

With a fleet of 17 Dreamliners, delivered in late 2011 before any other airline, All Nippon is the world’s largest operator of Boeing’s new jet. But that fleet remains grounded as US and Japanese investigators try to determine why a battery burst into flames and another spewed smoke in early January on 787s operated by All Nippon and Japan Airlines.
