When you can fly e.g. London to Barcelona for something like $59 (if you time your ticket purchase right), it is a bus, for the price of a long-range bus ticket.
(There is even a big aircraft company named "Air Bus", or something, did you hear about them?)
I've flown business class, it's still a bus, a nicer bus where you are treated marginally better, but it's a bus. Maybe private planes would change things (I've never been on one) but I can't imagine airplanes as being anything but a means to an end that I wanted to spend the least amount of time on.
