All Nippon AIrways (ANA) on Wednesday canceled all remaining Boeing 787 flights until the end of February.
This brings the total number of Dreamliner flights canceled by the Japanese airline to more than 1,200, including 951 domestic flights, and 255 international flights.
All 50 Boeing 787s worldwide remain grounded as authorities in the United States, Japan and France investigate a battery fire in Boston on Jan. 7 and a separate battery failure that forced a second 787 to make an emergency landing in Japan a week later.
ANA, Asia's top airline by revenue, lost more than $15 million in revenue from having to cancel Dreamliner flights last month. Earlier this week it said it was unclear as to when Boeing's sophisticated new plane would resume commercial flights, making it harder to predict the longer-term financial impact of having the plane idle.
