The grounded Dreamliner is "absolutely" safe and will be back in the air within weeks, planemaker Boeing said in Japan on Friday, as it sought to reassure airlines and passengers about its aircraft.

United Airlines said Thursday it expected to keep its six Boeing 787s out of service until May 12, as the cutting-edge airplane remained grounded worldwide due to battery problems.
