This assignment is an integrative study of the price discrimination strategy employed by Cathay Pacific Airways Limited. It begins with an abstract summarizing the core focus on price discrimination within the Hong Kong aviation industry, emphasizing Cathay Pacific's operations and service offerings, including ground handling, different flight classes, and loyalty programs. The paper investigates the company's price discrimination techniques, primarily third-degree discrimination, comparing its fare prices with competitors and evaluating its success through revenue and profit trends over a ten-year period. The study also explores the impact of incomplete information on market failure and concludes with recommendations for future pricing strategies. The research methodology involves secondary data collection and analysis using tables, graphs, and Excel software to interpret the quantitative data. The analysis covers how ticket prices vary across classes, elasticity of demand, and the company's overall performance, including a comparative analysis of ticket prices with competitors.
