I am skeptical that we will see a return to the freedom of travel and ease of movement we have been enjoying for the last 40 years. Airlines have been battered by this, the travel industry has been routed. Going forward portions of the former travelling population will be more conservative, travel insurance will be more complicated, all borders will open again but with a variety of restrictions. There will no doubt be discounted airfares for example to try and lure the travelling public back but those can only last for a short time before the reality of making air travel between countries viable. The cost of flying around the world I think will increase and with that there will be fewer people travelling. I just dont see a return to the normal we got used to.
