This thesis explores revenue management within the domestic United States airline market from a broad research base including peer-reviewed journals, professional articles, industry studies, government statistics, and consumer surveys. Among other topics, the thesis synthesizes data from these sources to effectively understand how airlines turn a profit in one of the world’s most competitive industries. Within that scope, the thesis explores the history of the industry, how technology affects revenue management strategies, how deregulation affected competition, and how different costs impact an airline’s operations. This is accomplished primarily with the literature review, governmental statistics, and professionals in the field. Moreover, the surveys provide a human element to these numbers. Namely, how does the public perceive the airline industry? Moreover, what drives the decision to purchase a seat on a particular airline over another? The research suggests four main trends in the US’ airline industry: increase in low-density long-range routes, high-density short-range routes, redefining high-density routes’ capacity utilization, and expansion of the Low-Cost Carrier. The former, due to the scope of this thesis, will be diminished in its analysis. The latter three will be expanded upon. A case study of three U.S. airports identified as small, medium, and large is present at the end to expand upon a hypothesis presented.
