This report presents a detailed analysis of airport arrivals and local economic impact for the Los Angeles five-airport region (LAX, BUR, SNA, ONT, LGB) over 2015–2024. It integrates three components: (1) regression models linking final-destination arrivals to hotel room revenue and accommodation-sector GDP; (2) a specification search identifying the optimal lag structure for monthly data; and (3) an event study identifying ten statistically significant turning and inflection points over the decade.
