Today, the plane flies with about 500 seats on the few global airlines that use it: Singapore, Emirates, Air France, Lufthansa and British Airways.
Korean Air, for example, puts only 407 seats on its A380.
Emirates' inaugural Dubai-Auckland service video:
"We're looking at optimising the space on this aircraft and making it more efficient," said Doric's managing director Mark Lapidus.
"It's a cash-printing machine for an airline that is using it correctly."
And that means more seats and a better return on each flight - to the point of potentially moving the crew rest quarters to the cargo hold, he said. A primary consideration in the new A380s will be seating density: whether to continue with a 10-abreast seat arrangement in the economy cabin or move to 11, with a 3-5-3 configuration.
That would add about 40 additional seats in the cabin. Emirates puts its first and business-class sections on the upper deck.
"I am sure Airbus is going to persuade us to do it," Emirates president Tim Clark told Aviation Week, with the airline's goal being to keep its coach-class seats at least 18 inches wide.
