Shell Aviation has expanded its branded FBO network with the addition of six Landmark Aviation facilities. The half dozen locations include Chester County G.O. Carlson Airport in Coatesville, Pa.; Rocky Mountain Metropolitan Airport in Denver, Colo.; Laredo International and Midland International Airports (Texas); Jacqueline Cochran Regional Airport in Thermal, Calif.; and Santa Fe Municipal Airport in New Mexico, all of which were among those acquired by Landmark in last year’s purchase of the Ross Aviation chain. “We have a mutually beneficial relationship with Landmark that began eleven years ago,” said Mike Allen, vice president of Eastern Aviation Fuels, Shell’s exclusive U.S. distributor of aviation fuel. “We are happy that our two companies have continued to grow together.”
