I absolutely agree with regard to the shortcomings of "Zooming" or Teams, there's a lot more to body language than facial expression, and in an ideal world face to face would revert pretty well to where it was. But again it depends upon the sector, large infrastructure or civil engineering projects are going to need boots on the ground at management and executive level more so than straight buying and selling of product, and particularly services. Large businesses (the publicly quoted ones) are wedded so much to financial performance and cost cutting is going to be key to that. Top of the list for getting the axe are things like staff welfare (canteens, perks etc) followed by business travel, bet that domestically or internationally. Things are going to be more than a little tight for the foreseeable future, and at very best some of the front-end business passengers may find themselves down the back with the plebs and that isn't going to be good for airline revenues.
