Boeing on 9 November rolled out the first 787 produced at the higher rate of five aircraft per month.
The Seattle airframer says it is on course to achieve a build rate of 10 Dreamliners per month by late 2013.
Mike Sinnett, vice-president and chief project engineer for the 787 programme, says: "The airplanes are coming down the line much more efficiently than they were. Our crews are learning and the production issues we have had are behind us now."
Its production ramp-up has been aided through the opening of a surge line earlier this year at Everett and a second final assembly facility at Charleston, South Carolina.
Employee initiatives have also helped the move to the higher rate, it says. Some 500 teams are working on improvement initiatives, says Boeing.
The aircraft is the 83rd Dreamliner to be built.
