> air travel is already something everyone (in the developed world) can afford

Ship travel was already something most people in developed countries could afford. What’s the use of getting around faster and higher off the ground?

A Transatlantic crossing took around ~ 100 hours, whereas a plane takes ~ 7 hours. So, we are talking about an order of magnitude improvement.

It's hardly the same thing with a supersonic airliner, which just reduces the time in roughly half.

However, the first commercial passenger transatlantic flights took 29 hours, on the Panam B-314.
