Like all airports Bangkok Suvarnabhumi is about timing. I arrived about midday from Singapore and went from an economy class seat on the plane to Sukhumvit Road in a little over 1 hour. At passport control there were about 6 people in front of me and an airport staff member ushered us and others to the empty ASEAN counter. My baggage was there after a quick bathroom break and zero queue for the taxi. Checked in to depart around 3.00pm to no queues at either passport or security channels. Plenty of facilities in a clean terminal with friendly staff. Yes, the walks can be long and for that a 9 not a 10.
