"First of all, you have to remember that on long-haul, the front cabins pay for the flight; if you scale the plane up without also scaling up the number of people buying premium-cabin tickets, you lose money." Singapore airlines has a full upper deck business class configuration. More space just means you have more space for business and first class too. "Second, there still just aren't enough places on earth that can fill a 500-seat (or even 600-seat as Emirates is experimenting with on their latest configuration)" While I'd agree that there are not that many business cases for such a huge plane there definitely are. Especially in the case of mega connectors like Emirates. Emirates offers two daily flights from Zurich, which is a European 2nd tier airport with just shy of 30M yearly passengers, while Singapore airlines compressed their two daily flights into one A380 flight a day. "You may not like it, but the more reasonably-sized twinjets won. 250-350 seats is the sweet spot, and the future belongs to 777s, 787s, A350s and their descendants." We'll see when Asian airports (especially in China) run out of runway capacity. There are only so many flights you can dispatch over a runway in any given time.
