People fear all sorts of things when flying, to crash, bombs on board and now infections. Irrational or not, it's better to not blame them for it or call them stupid but deal with their fears. Travel means many people in tight spots, security lines, people movers, cabins. The entire travel environment is just not set up for any separation. On the other hand practically people just cannot travel to many places as borders are closed or only half open and many people don't have the money to spend now. Corona is far from over it looks like at least local hotspots are coming back. This will go on for a while it seems.
