No brainer of a decision - Suvarnabhumi really wasn't clicking. I think I've been through about 10 times so far and ended up getting bussed to the gate on 3 occasions, but never could work out why - without realizing some of the the Taxiways were unusable and a few of the piers were unserviceable. It's going to be difficult for passengers making domestic connections.
I was astonished reading the earlier posts to learn that the airport had a capacity of around 40 million passengers / year. ICN, which I use a lot, has physically a much larger terminal building than BKK and has a current capacity of around 30 million. ICN is undergoing Phase 2 expansion to 44 million - but the difference is that ICN works and sadly BKK doesn't... Oh yes - and there's a Golf Driving Range by the ICN Hilton and a rather nice full coure down the road.
