Dr., this is Captialism; that level of empathy is toxic.

Yes, we're human beings, so airlines do a different pricing strategy, where everyone pays the same price and everyone gets the same amount of space.

Then you can pay more for your ticket. Simple fact is, to save money on fuel, the airline has to use the smallest possible airplane and have high seat density. Luxury airlines like Emirates or Etihad might have lower seating density but you'll pay extra for the tickets.

Emirates CEO is asking Airbus to start building the A380 again, but in a new more fuel efficient version. Even gave them some design ideas. Reason being, that huge-ass plane can be better optimized for comfort due to economies of scale. Unfortunately I think they're using a lot of that space for first class, which gets showers and shit.

In the US, supposedly JetBlue has more space in economy than the big 3 tend to. Willing to bet it's more expensive too, but I wouldn't know, I've only flown European airlines and cheap to midrange ones at that.
