Some of the consequences of the Covid virus are more obvious than others. Let’s start with them.
If you have travelled a bit internationally (and I don’t mean just to the country next door) you’ll be familiar with what airlines call the “hub and spoke” model of travel. Essentially, you fly from where you are to the airline’s central hub (or that of one of their partners) and then on to your destination. This may not be ideal for you, unless you like hanging around duty-free shops and drinking expensive coffee, but it’s good for airlines, who can use smaller planes making shorter flights, and simplify their logistics.
But more than the (in)convenience, what’s interesting here is the model of interaction. Say I am an NGO worker in South Sudan, going home to Copenhagen. I catch a plane from Juba to Addis Ababa, a major hub for the region, then catch a plane to Munich, another major hub, then on home. At Addis, I bump into someone who is coming from Khartoum, and going to Dubai, to take a plane to Islamabad. In Munich, it’s someone from El Salvador, who’s arrived via Mexico City and Washington, and is going on to Warsaw. You get the picture.
But a lot of airlines don’t. And this is the problem with the”back to normal” idea. So long as the virus exists anywhere in the world, there is a measurable chance that air travel will spread it everywhere, without a level of control and testing that isn’t possible now, and may never be.
So long, international air travel. You were (occasionally) fun.
