I like the entertainment situation on Singapore Airlines. They have Radiohead, Yeasayer, and Them Crooked Vultures albums. Also, lots of boring movies. I guess I don't really like the movie part but am impressed by it.
I like Incheon airport. It only takes about 10 minutes to get out of there. I've never arrived there and had to wait more than 5 minutes for my things at the baggage check. Most efficient and clean airport I've seen.
