The airline industry is a dynamic industry with intense competition. Deregulation, the international competition structure, and economic and COVID-19-like crises make the sector even more fierce. In this chapter, airline industry competitive strategies are discussed. For this purpose, following the introduction part, the concepts of strategy, business strategy, and competitive structure of the airline industry are discussed, and the place of competitive strategies in business strategies is explained.
