The A380 was planned for a world where people travel between big hubs before hopping to another flight to reach their destination. That world exists only for a small amount of destinations and for most other routes the A380 would be mostly empty and therefore widely uneconomical to use. Instead bireactor planes are now allowed to travel further and further away, making region to region traffic a lot more realistic than 20 years ago. And that is where the traffic is increasing the most.
