An airship would be something in between. They can be spacious enough for moving around inside while traveling and you can easily make stops at sightseeing destinations (airplanes use most fuel for starting, while that is essentially free with airships).
Time critical business travel would be probably not possible to replace, but as the pandemic has shown, those can be mostly replaced with online meetings anyways.
Now compare that to an airplane that can easily go x4 that.
Sure, but compare that to a cruise ship (which is the fairer comparison) which goes 4x less fast.
People don’t use cruise ships to travel. They use them for vacationing.(like a floating hotel)
