Abstract This paper proposes to use confirmatory factor analysis (CFA) to evaluate the relationship between six observed variables (arrival and departure counts, arrival and departure demand, taxi-out and airborne delays) and their underlying latent (unobserved) constructs (operations, demand, and delays) at six of the most delayed airports (EWR, JFK, LGA, MIA, ORD, and SFO) during the calendar years of 2006–2008. The CFA revealed a good fit between the six observed variables and the three factors that may explain on-time performance except in the case of JFK. The use of CFA can help analysts validate constructs when theory supports a priori predictions and relationships between observed and unobserved variables.

    Highlights Confirmatory factor analysis is used to validate the relationship between observed variables and unobserved constructs. The study evaluates six cases of the most delayed airports (EWR, JFK, LGA, MIA, ORD, and SFO) from 2006 to 2008. The underlying latent or unobserved constructs are operation counts, demand, and delays. The CFA revealed a good fit between the six observed variables and the three factors except in the case of JFK.
