We experience air traffic delays every day, but are there any recurrentpatterns in these delays? In this study, we investigate the recurrence of delaypropagation patterns in Japan's domestic air transport network in 2019 byintegrating delay causality networks and temporal network analysis.Additionally, we examine characteristics unique to delay propagation bycomparing delay causality networks with corresponding randomized networksgenerated by a directed configuration model. As a result, we found that thestructure of the delay propagation patterns can be classified into severalgroups. The identified groups exhibit statistically significant differences intotal delay time and average out-degree, with different airports playingcentral roles in spreading delays. The results also suggest that some delaypropagation patterns are particularly prominent during specific times of theyear, which could be influenced by Japan's seasonal and geographical factors.Furthermore, we discovered that specific network motifs appear significantlymore (or less) frequently in delay causality networks than their correspondingrandomized counterparts. This characteristic is particularly pronounced ingroups with more significant delays. These results suggest that delayspropagate following specific directional patterns, which could significantlycontribute to predicting and controlling air traffic delays. We expect thepresent study to trigger further research on recurrent and non-recurrentnatures of air traffic delay propagation.

Is air traffic delay propagation recurrent?
