Seoul Incheon is super - a virtual city in an airport. My ? is - why do their people movers not go both ways? The transit areas on the 4th floor are very impressive, but where's the swimming pool?
Did Skytrax even consider our wonderful airports in the Pacific Northwest? Seatac and Portland are pretty darn impressive when compared to the average American terminals.
The airport that also impressed me was Ton Son Nhat Airport in Saigon (HCMC) - quite modern, clean and up-to-date for such a developing country.
