Abstract Purpose: The purpose of this study is to examine and compare the financial performance of IndiGo Airlines and Emirates, identify how their different business models influence profitability and efficiency, and evaluate their long-term financial sustainability and competitive position in the global aviation industry. Research Methodology: The study adopts a hypothesis-based research methodology, using quantitative financial data from secondary sources such as annual reports and published financial statements of IndiGo Airlines and Emirates. Financial ratios and performance indicators are analyzed to test formulated hypotheses and draw comparative conclusions about profitability, efficiency, and financial sustainability. Findings: The results of the study reveal that IndiGo demonstrates higher cost efficiency and stable profitability due to its low-cost business model, while Emirates shows higher revenue generation driven by its global network and premium services. Emirates has stronger asset base and international market presence, whereas IndiGo maintains better operating margins through effective cost control. Both airlines show financial resilience, but their strengths differ—IndiGo in operational efficiency and Emirates in scale and market diversification. Implications: The findings highlight how different business models significantly influence financial performance in the airline industry. The study provides insights for airline management in optimizing cost structures and revenue strategies. Investors and policymakers can use the results to assess financial sustainability and competitiveness across low-cost and full-service airlines. Originality: The research is based on self-formulated methodology. All references are duly cited and all the information is collected by the research on their own.
