KUALA LUMPUR, Malaysia (AP) — Southeast Asia’s top budget carrier, AirAsia, says it may dissolve its partnership with Japan’s All Nippon Airways Co. amid clashes over how to run their low-cost joint venture airline.

AirAsia says its Japanese affiliate has been facing challenges due to a “difference of opinion in management, most critically on the points of how to operate a low cost business” and operations from Narita airport.

It says AirAsia Japan has failed to meet its business targets “due to the inability to manage costs” since its launch in August last year.

AirAsia said Tuesday it would not rule out any options “including dissolution of the joint venture.”
