(Adds CEO comment, details)
Sept 13 (Reuters) - Boeing Co will raise production of 787 Dreamliner passenger jets to 14 a month in 2019, CEO Dennis Muilenberg said on Wednesday, pressing ahead with plans that had been placed on hold as the company gauged demand for wide-body jets.
The company's shares rose as much as 1.20 percent to $243.46 on Wednesday.
Muilenberg's comment comes at a time when the company is slowing 777 output ahead of transitioning to a new model and signals the aircraft maker's confidence in rebounding demand for wide-body planes.
"Based on existing backlog, we're confirming now that we are going to build 14-a-month production rate in 2019," Muilenberg said at a conference organized by Morgan Stanley.
"We expect to add 100 airplanes to the 787 block. That will factor in to the financials and is accretive to our margins," he said at the event.
The decision to raise output from 12 a month closely follows Boeing's preliminary deal to sell eight of the jets to Malaysia Airlines..
Through August, Boeing has won 78 net 787 orders this year.
