How do you have a large conference on zoom? How do companies display their product? How can you taste food? Sit in a new car or boat etc?
Business travel isn’t just some suit travelling to sign a contract, it’s so much more than that. Yes zoom, will have a place but airlines will adapt and won’t really care who sits in the comfy seats, as long as their paying for it who cares?
as for the melon talking about Concorde above, any volunteers for hitting him with his own dumb stick? Pretty sure no one cared about telecommunications on those LHR-BGI flights we used to do. Maybe the years have clouded my brain but I recall it was more the fact it couldn’t go supersonic over land so was heavily restricted on the routes it could fly to turn a profit. That and after the french went and crashed one, the increased weight due to the modifications in the wing tanks made it more challenging to reach JFK westbound in one go.
