I don't think it's correct to label this a black swam event. Pandemics are known to occur repeatedly, we had lesser ones in the 20 years and major international organizations were planning for them. The whole world were looking at china and with a seeing did nothing, including the airlines. Well, not everyone, just most. Some countries did shut down travel to and from china immediately and instated screening. Had airlines shown the same foresight as those countries they could have shut down service to china as a "supportive measure" for the containment and enjoyed continuing profits in the rest of the world. They didn't. Perhaps this is a matter of biases and misaligned incentives. In europe airlines were even flying empty just to retain their airport slots. But biases and incentives just mean you're very much aware of the black swans in front of you, you're just ignoring them willfully. Relabeling these things as black swan events does a disfavor to everyone because they can just throw up their arms and say it was higher force instead of reflecting on the deeper structural issues instead of just working on specifically pandemic-related ones.
