In July, test engine trouble was the subject of a probe by the U.S. National Transportation Safety Board. The same month ANA said it was grounding five Dreamliners for repairs because of a defect in the Rolls-Royce engine.

In February, Boeing said about 55 Dreamliners were at risk of developing a fuselage problem.

Undeterred, ANA said in September it was ordering 11 more 787s in a deal with a list price of around $2.68 billion that will eventually take its fleet of Dreamliners to 66.

ANA shares on Tuesday rose 0.54% to 185 yen in Tokyo while Japan Airlines was down 0.68% at 3,610 yen.

The two airlines faced more problems with the heavy snowfall that hit Tokyo on Monday, cancelling more than 460 domestic flights.

On Tuesday a total 37 domestic flights were cancelled and dozens of others were delayed.
