The negative of the 380...is that you have to fill seats, and when you are talking about 800 seats on a daily basis, you really don’t need that many around the globe.
An 800-seat airplane is a terrorists wet dream.
“The A380 was initially offered in two models: the A380-800 and the A380F. The A380-800’s original configuration carried 555 passengers in a three-class configuration or 853 passengers (538 on the main deck and 315 on the upper deck) in a single-class economy configuration.”
