Spirit, and Boeing’s Wichita commercial airline division before it, have built the fuselages for all 8,000 planes.
Spirit builds the fuselage, pylons and thrust reversers in Wichita and wing components in Tulsa.
Boeing has more than 3,700 Boeing 737′s on order. That includes 1,934 orders for the 737 MAX, an upgraded version with new engines.
The 8,000th 737 was delivered to United Airlines. Since 1965, United has taken delivery of more than 550 737s.
Boeing has been raising 737 production with continued rising demand.
Since 2010, it’s increased production from 31.5 planes a month to today’s rate of 42 per month. It’s planning production increases to 47 a month in 2017, and has hinted that production could be raised beyond that.
“The 737 program continues to innovate with new features and technology, meeting the needs of our customers now and into the future,” Beverly Wyse, Boeing vice president and general manager of the 737 program, said in a statement. “Boeing has a long and treasured history with United Airlines, and we’re proud they’re taking delivery of this milestone airplane.”
