This research investigates the number of on-time flights (OTFs) at European airports and how this number is influenced by an airport's flight connectivity. We conduct a spatial statistical analysis of the spatial context relationship using econometric models, and the interaction between the number of airport's on-time flights (OTFs) and flight connectivity. Using 2017 and 2018 data, we characterize the relationship between a European airport's air connectivity index (ACI) and the number of flights that depart or arrive at a gate within 15 min of schedule (OTFs). We also analyze the relationship between OTFs at a given airport and those of neighboring airports. As the distances between airports increase, autocorrelation shifts from a positive to a negative sign meaning that at greater distances, airports' on-time performance is less dissimilar. We find that before the pandemic and the ensuing global travel shutdown, a spatially lagged term of ACI improves the model's ability to account for variations in OTFs across airports. Flight delay propagation in the air transport system caused delays to occur due to the shared resources underlying an initially delayed flight and subsequent flights. This analysis offers a rational for increasing airport connectivity as a way of improving the share of on-time flights of European airports.
本研究调查了欧洲机场的准点航班数量，以及该数量如何受到机场航班连通性的影响。我们使用计量经济学模型对空间背景关系进行空间统计分析，以及机场准点航班数量与航班连通性之间的相互作用。利用2017年和2018年的数据，我们刻画了欧洲机场的航空连通性指数（ACI）与在计划时间15分钟内离港或到港的航班数量（准点航班）之间的关系。我们还分析了给定机场的准点航班与相邻机场准点航班之间的关系。随着机场之间距离的增加，自相关性从正号变为负号，这意味着在更大的距离上，机场的准点表现差异较小。我们发现，在疫情及随后的全球旅行停摆之前，ACI的空间滞后项提高了模型解释各机场准点航班变化的能力。航空运输系统中的航班延误传播，由于最初延误航班及后续航班所共享的资源，导致延误发生。该分析为增加机场连通性提供了一个理由，作为提高欧洲机场准点航班份额的一种方式。
