The travel and tourism industry was one of the fastest-growing industries before the onset of the COVID-19 pandemic. However, to avoid COVID-19 spread, the government authorities imposed strict lockdown and international border restrictions except for some emergency international flights that badly hit the travel and tourism industry. The study explores the nexus between international air departures and the COVID-19 pandemic in this strain. We use a novel wavelet coherence approach to dissect the lead and lag relationships between international flight departures and COVID-19 deaths from January 2020 to September 2020 (COVID-19 first wave period). The results reveal that international flights cause the spread of COVID-19 spread during May 2020 to June 2020 worldwide. The overall findings suggest asymmetries between daily international flight departures and COVID-19 deaths globally at different time-frequency periods due to uncertainty surrounding the COVID-19 pandemic. The study will be conducive for the policymakers to control the upsurge of COVID-19 spread worldwide.
在新冠疫情爆发之前，旅游业是增长最快的行业之一。然而，为避免新冠病毒传播，政府当局实施了严格的封锁措施并限制国际边境，仅有一些紧急国际航班除外，这对旅游业造成了严重打击。本研究探讨了在这种情况下国际航班离境与新冠疫情之间的联系。我们采用一种新颖的小波相干方法，剖析了2020年1月至2020年9月（新冠疫情第一波期间）国际航班离境与新冠死亡病例之间的领先和滞后关系。结果显示，2020年5月至2020年6月期间，国际航班在全球范围内导致了新冠病毒的传播。总体研究结果表明，由于新冠疫情的不确定性，全球不同时间频率段的每日国际航班离境与新冠死亡病例之间存在不对称性。该研究将有助于政策制定者控制新冠病毒在全球范围内的传播高峰。
