When assessing these applications, we generally conduct a two-step analysis of the foreign air agreements that have been submitted to us for approval. The relationship between U.S. and foreign airlines plays an important role in the participation and competitive position of the U.S. aviation industry in the “global” market. A study by the Office of Aviation Analysis served as the economic basis for the development of the department`s international aviation policy to promote international alliances and spread the benefits of deregulation to global markets. As a result, codeshare agreements between U.S. airlines and foreign airlines have grown significantly, as have broader alliances of U.S. carriers (cooperative service and marketing agreements) with foreign airlines. While the ministry does not support the study, its methods or conclusions, it has been tasked with advancing independent and academic research to evaluate alliances of immunized airlines. Much of the competition in the aviation industry is for ticket sales strategies (also known as “seat reservations”) (revenue management, variable pricing, and geo-marketing). . .
