Re: This underlines one more thing
To my understanding, two things put the brakes on the A380: ETOPS and NEO.
New ETOPS rules (Engine Turns Or Passengers Swim), originating (who would have guessed) from the USA led to a lot of new competition that the A380 had not been designed to deal with. NEO led to savings making these competitors being cost competitive. On top of it, there are not enough airports with the infrastructure required to handle the A380 efficiently.
An A380 NEO might change the picture.
