An expansion by Lufthansa Technik Component Services is expected to bring 500 jobs to Tulsa. Groundbreaking was yesterday for the airline's western hemisphere operations at Tulsa International Airport. Lufthansa is the world's biggest non-American airline group, serving a quarter of the world's commercial fleet. A third of Lufthansa's aircraft get their parts repaired mostly in Tulsa. The company plans to move its administration department and avionics workshop to Tulsa from Miami. The 140,000-square-foot expansion is expected to be up and running by 2030.
