in my opinion, the a380 or anything as big is becoming less optimal for today's passenger loads and flight routes. it will go the way of luxury and pleasure niches....such as sleeper flights with personal cabins, luxury suites, in-flight casinos, in-flight nightclubs, ktv lounges, high class brothels, harem, spa, swimming pools, steam baths, massages, f*ckshop, etc.
due to extreme wealth flowing between east and west, there's a business case for that. using an a380 to compete with smaller, more efficient and more modern aircraft to maximize passenger loads and minimize fuel consumption on popular routes is like using a luxury cruise liner that can accommodate 3000 passengers to compete on routes frequented by ferries. it should be remodeled to ply like a luxury cruise liner of the skies, for the wealthy holidayer who's willing to pay an average usd5000 per pax so he or she can enjoy fine dining, gambling, spa and mind blowing sex in the sky while flying to a destination 12 hours away.
