Do airlines have legal obligations to manage the risk of in-flight infections?
In the pre-COVID era, I answered this question affirmatively. In a 2016 paper, I reviewed the scientific literature showing that airline travel is a key vector for spreading infectious disease, both because airports and airplanes tend to mix people in such close quarters that they are likely to infect each other, and because it efficiently distributes infected people around the world to then infect more people.
