In my opinion, based on general reading and observations, Zoom has seriously shifted perception of the value of in-person meetings. Some routine business travel for meetings will remain valuable; much will be considered unwarranted, both in terms of cost and, until there’s a vaccine, risk. More things that can be accomplished remotely will be.
I think leisure travel will also wait for a vaccine. The loss of hotels, restaurants, retail and visitor attractions will make many destinations less comfortable and less appealing.
Airlines struggling to survive will cut costs, making flying suck even more. Bring your own sandwich to the airport. Check and recheck your rental car reservation, maybe make more than one.
