Airline delay propagation: A simple method for measuring its extent and determinants
提出一种简单方法，通过比较前序航班到达延误与后续航班地面缓冲时间，识别传播性离港延误并衡量其对到达延误的贡献，实证发现其贡献取决于若干关键因素。
This paper offers a simple approach for identifying propagated departure delays and measuring their contribution to arrival delays. Under our approach, a propagated departure delay occurs when the arrival delay of the inbound flight exceeds the subsequent flight’s ground buffer. The size (or frequency) of such propagated delays relative to the size (or frequency) of arrival delays then measures the contribution of propagated delays to late arrivals. This approach differs from earlier attempts to quantify the contribution of delay propagation since it focuses on an individual flight and its immediate predecessor, without attempting to trace the sources of delay propagation back through the entire sequence of prior flights. The paper’s empirical results show that the contribution of propagated departure delays to arrival delays depends on several key determinants.
