In this paper we apply an index of interconnectedness to air transport networks. We study empirically how service quality, measured in average minutes of arrival delay, differs between network structures operated by European airlines. We observe that airlines with contrasting business models, low-cost carriers versus full-service carriers, prefer different network types. We run panel data fixed-effects on a sample of over two million flights that were operated in Europe between April 2015 and March 2016. Our main finding is, that airlines are more successful in managing delay when they operate a network with hub-and-spoke characteristics, especially if flights originate at one of their own hubs, compared to airlines that operate a network with point-to-point characteristics. Our findings support the hypothesis that at hubs, where the carriers have a dominant position, airlines internalize congestion into their own operations.

在本文中，我们将互连性指数应用于航空运输网络。我们凭经验研究服务质量（以平均到达延误分钟数衡量）在欧洲航空公司运营的网络结构之间有何不同。我们观察到，商业模式不同的航空公司，低成本航空公司与全方位服务航空公司，更喜欢不同的网络类型。我们对 2015 年 4 月至 2016 年 3 月期间在欧洲运营的超过 200 万个航班的样本运行面板数据固定效应。我们的主要发现是，航空公司在运营具有枢纽和-的网络时更成功地管理延误与运营具有点对点特征的网络的航空公司相比，辐条特征，特别是如果航班起源于其自己的枢纽之一。我们的发现支持以下假设：在枢纽，
