This study evaluates the attractiveness of self-hubbing in terms of the (a) symmetry of itineraries and the consequences for passengers in the case of missed flights. We compute the most attractive European origin-destination (O-D) pairs through self-connection and evaluate their robustness by estimating the expected delays relative to connecting times and the travel options available when a connection is missed. Results show that the potential of self-connecting markets is reduced when accounting for asymmetrical travel options and the consequences for travelers in the case of missed flights. In terms of frequencies, self-connecting passengers are, on average, found to have fewer alternatives to complete a given O-D pair than in the case of alliance-based connections (− 33%). Our findings moderate the confidence of past evidence on self-hubbing in light of the concrete reliability of self-connections for passengers. The itinerary choice made by passengers inevitably depends on the evaluation of travel quality attributes related to the (a) symmetry of the itineraries and the costs incurred through missed connections.

谨慎管理：欧洲机场网络中自我联系的脆弱

这项研究根据（a）路线的对称性以及在错过航班的情况下对旅客的后果，评估了自架飞机的吸引力。我们通过自连接计算出最有吸引力的欧洲原点-目的地（OD）对，并通过估计相对于连接时间的预期延迟以及错过连接时可用的旅行选择来评估其坚固性。结果表明，考虑到不对称的旅行选择以及错失航班给旅客带来的后果，自我连接市场的潜力降低了。就频率而言，与基于联盟的连接相比，平均而言，发现自动连接的乘客完成给定OD对的备选方案更少（-33％）。鉴于乘客自我连接的具体可靠性，我们的发现减轻了以往关于自我颠簸的证据的信心。乘客的行程选择不可避免地取决于对与（a）行程对称性和因错过接驳而产生的费用有关的旅行质量属性的评估。
