Abstract This research paper examines the operational resilience and HR-Finance interface of IndiGo Air- lines during the significant crew shortage crisis observed at Pune and Mumbai airports in early 2025. The study investigates how "lean staffing" models, initially designed for cost efficiency, tran- sitioned into "fragile systems" under the pressure of surging post-pandemic travel demand and localized operational bottlenecks. Through a quantitative analysis of 158 airline personnel and ground handling staff, the research evaluates the impact of resource optimization on service de- livery and employee burnout. Literature review of 15 recent studies (2018-2025) provides the the- oretical foundation for understanding the tension between financial frugality and systemic robust- ness. Using advanced statistical methods, including Multiple Regression and One-Way ANOVA, the study tests hypotheses related to staffing levels and crisis response efficiency. The findings reveal that while lean models offer high profitability during stable periods, they lack the "slack" necessary to absorb shocks like mass sick leaves or technical delays. The paper concludes that a hybrid "Resilient-Lean" model, supported by strategic financial reserves for emergency man- power, is essential for maintaining Indian aviation standards in volatile contexts.
