All these years later, there is still chaos at Suvarnabhumi International Airport, depending on your arrival time.
Morning seem to be the best arrival times to make it through immigration counters the quickest.
Those flight arriving around midnight may be queued in the arrival lines at immigration for 2+ hours.
Standing in line for 2 hours after an international flight is tremendously painful.
Then there is still luggage collection and proceeding to transportation.
