The dynamic nature of the airline catering industry, characterized by evolving consumer expectations and the imperative for operational efficiency, underscores the need for a strategic, data-driven approach to management. This research delves into the implementation and impacts of Key Performance Indicators (KPIs) within airline catering, aiming to enhance operational efficiency, customer satisfaction, and environmental sustainability. Through a mixed-methods approach, the study identifies critical KPIs, gleans insights from successful case studies, and conducts a comparative analysis across various airlines and regions. Findings reveal that meal preparation efficiency, on-time performance, customer satisfaction scores, and food waste percentage are pivotal in driving performance improvements. The research contributes to both theory and practice by applying service management theories, operational efficiency frameworks, and sustainability concepts specifically to airline catering. Strategic recommendations are provided for integrating technology, focusing on customer-centric metrics, and adopting sustainable practices. Future research directions include exploring technology integration, cultural and regional impacts on KPI prioritization, and developing comprehensive sustainability metrics. This study not only highlights the significance of a KPI-driven approach in advancing airline catering services but also opens pathways for further academic inquiry and practical innovation.
