Once governments get out of the way, the industry can pick up. There has to be a lot of pent up travel demand. Loads of people travelled home from the country they worked, halfway around the world. Those people will probably need to return to that work. Lots of separated families will want to reunite. Remote working and virtual meetings don't cut it for making deals, or university courses, or buying, or any of the myriad reasons people travel for business. There is demand for leisure travel.
We have to be patient.
