The popular single-aisle airplane will be delivered to China Southern Airlines, headquartered in Guangzhou, China, next week.
The 737 jetliner is important to Wichita-based Spirit AeroSystems, which builds the fuselage, strut, pylons and wing components. Spirit receives half of its revenue from the program.
“The Next-Generation 737′s success is the result of years of expertise that thousands of employees continue to build into every Boeing 737 used in private, government and commercial service,” Beverly Wyse, Boeing vice president and general manager of the 737 program, said in a statement. “It is an incredible milestone to be delivering our 4,000th Next-Generation 737. We thank China Southern Airlines and all our customers who have made the 737 the world’s most popular jetliner.”
