Meh. I was a Don Muang regular back in the day and, while hardly eye candy or a Changi-beater, it was actually a pretty darn functional airport, especially if you had lounge access and didn't need to camp out in the corridors. DMK's few notable warts (messy taxi system, random long queues at immigration, looooooong walk from international to domestic terminal) haven't been much improved by Swampy. Pretty much the only upsides are that I've yet to get stuck in an incoming taxi jam before the terminal at the new BKK, which was an all-too-regular occurrence at DMK, and that I'm cautiously optimistic about the new train link.
