We use public data on 73 airlines operating worldwide over the period 1996–2011. In estimating the impact of leasing on profitability, we control for potential endogeneity by applying robust instrumental variables estimation, while introducing a set of individual and macroeconomic factors. Our results are threefold. First, we identify a non-monotonic and concave effect of leasing on an airline’s profit margin, suggesting decreasing marginal returns to leasing in this sector. This is an original finding for the industry. We also derive a confidence interval for the optimal level of leasing. Second, we show that the impact of leasing on an airline’s operating profit is stronger for Low Cost Carriers than for Full Cost Carriers: deviating from the optimal level of leasing might be more harmful for a LCC than for a legacy carrier. Finally, we analyze how an airline’s experience affects the relationship between leasing and profitability. Keywords: Leasing, Performance, Profit, Airline Industry 1. Introduction Airlines’ strategies are mainly driven by decisions on their network, products, prices and resources (specifically their fleet). As aircraft represent a long lifetime asset (25 years or more) and require a high investment, decisions on the fleet composition are the most engaging ones. Operating leases, as opposed to financial leases or ownership, allow airlines to recover some flexibility when making these fleet decisions. Indeed, a leased aircraft can be operated for a period lower than its useful life, with limited upfront capital requirement. With operating leases, unlike financial (or capit
