Japan's All Nippon Airways (ANA), the first Boeing 787 customer, said on Thursday a delay in first delivery dates for Boeing's Dreamliner aircraft would not have a huge impact on its operations.

Boeing said on Wednesday that first deliveries of the plane would be delayed by at least six months to late November or December 2008.

ANA spokesman Shinichi Shinkawa said the airline is still studying whether the delay would have any impact on its business plan.

ANA was hoping to ferry passengers to next summer's Beijing Olympic Games in the first planes of its planned 50-strong 787 fleet.
