Initial hopes for a quick disappearance of COVID-19 seem to fade away gradually, partially due to the emergence of new virus variants, which come with an inherent possibility for breakthrough infections. In this study, we take the recently emergent variant of concern B.1.1.529, labeled as Omicron by the WHO, as a motivating example for analyzing the possibilities flight bans provide for effectively containing the disease spreading process of such variants before they become widely spread. We compare several flight ban strategies including source-targeted bans, spatial neighbor bans, and flight neighbor bans, under varying simulation parameters. We hope that our results contribute to our aviation system becoming more pandemic-resilient.
