I got a few concerns about the A380....I'm actually not certain it'll live up to the hype, but love the idea....think about this....
1. You got 800 people loading and unloading; that'll take a huge amount of time adding to the trip. Loading a 300 person plan is a cinch, but 700+ plane an albatross;
2. Very Few aiports in the Asian developing world (I don't say "third world") can handle it, aside from Tokyo and Singapore, as far as I know. Don Muang probably can, thank God! But airport alteration costs big money. Airports would need "double-decker" four or more gangways to load or exit the thing, instead of one or two; two 747s loading simulateneously would beat it hands down, each going more direct;
3. You won't get your desired or best frequent direct flights, (except from NY-London, Tokyo-Singapore, Tokyo-LA or NY-LA) because such large loads are based on "hub-and-spoke" systems, as you'll then need commuter lines to take you where you REALLY want to go, causing way more change-overs on your way;
4. "Some" say the A380 is fuel inefficient, and I don't believe it's more efficient. If it's the the same efficiency, they'd need 550+ bookings for a flight to cover costs with such a big bird, same as the current 747, which will make money for the same load. See: http://www.boeing.com, http://www.airbus.com.
5. For ourselves, if we are all trying to get smaller, more direct routes on the ground, then it's the same in the air...compare to getting a direct taxi or limo to a bus on the ground; how do YOU go from Bangkok to Pattaya, in preffered circunstances? For 1,000 Baht, it's short time to him too...
6. The 747, an established plane, can handle 550 passengers as it is now, in a proven plane. JAL loads them as such all the time for Asia routes. Not all that much difference difference in capacity; and an A380 is twice the price, no increase in fuel efficiency. The A380 is very expensive for pretty much the same-same. Between fuel costs and capital costs for the A380, I don't think it's a great savings at all.
7. PERKS: casinos, bars, showers on board...what have you. The 747 tried that, and now uses that space for seats. If you gonna play in transit, TAKE A CRUISE! If you're on a long flight, you take an Ambien and a nap!
I think the future of aviation is less cattle-car, more direct and quick for the same efficiency. I'm not saying this as a Yank supporting Boeing, but as a practical traveler.
