All Nippon Airways Co. said Thursday it will postpone the debut of the Boeing 787 Dreamliner jet on international routes to January due to delayed aircraft deliveries.

The debut had been set for this month. ANA said one of two jets ordered for use on international routes is expected to be delivered by the end of the month, but it is not yet determined when the second aircraft will follow.

ANA said it won't use of the state-of-the-art aircraft on flights this month from Tokyo's Haneda airport to Beijing, but will fly it on the route on Jan. 14, 17 and 18.
