Boeing delivered an average of six 787 Dreamliners a month during the first quarter of this year, the company announced last week.

Total deliveries through March 31 were 18 for the aerospace giant's newest passenger jet, which is assembled at factories in North Charleston and Everett, Wash.

The company did not break out how many planes came from each 787 manufacturing plant.

For the same quarter last year, Boeing delivered one Dreamliner.

The number of all Boeing commercial aircraft picked up by airlines and other customers was 161 for the quarter, an increase of about 18 percent from a year ago.

The bulk of the newly filled orders - 115 - were for the 737 Next Generation jetliner, Boeing said. The 28 other deliveries were for the 777 and the 747.

Boeing outpaced rival planemaker Airbus, which reported 141 deliveries through March 31.

Separately, Boeing announced one of its first Dreamliner deliveries of the second quarter of the year Friday, when Kenya Airways picked up its first 787 from Paine Field in Everett for a 7,800 nautical mile nonstop flight to its home base in Nairobi at Jomo Kenyatta International Airport.

An update on the 787 is expected April 23, when Boeing CEO Jim McNerney and finance chief Greg Smith discuss the company's quarterly earnings.
