There is an online resource for tracking airline flights: Flightaware. It is fascinating to see the planes move in real time. You get a sense of how important air travel and freight is for all of us.
You also get a sense of how many flights are still going to and leaving China right now.
Today I read that British Airways has ceased direct flights to China. I’m sure that’s partly due to those flights now being mostly empty.
Wanna go to China, anyone?
I checked FlightAware just now. It’s night there, of course, so the rhythm of flights from the Left Coast of these USA hasn’t started to beat yet, and more is head to China than coming at this hour. Still, note the concentrations around Hong Kong, Bangkok, etc.
