The last trip of taking SQ got me see the terminal 3 of Changi Airport. Seen some improvement of the shuttle train from 15 minute interval to 5 minute. A butterfly garden and a fish pond to entertain guests during transit time. Big hall and a high ceiling, but the premium lounge for priority pass and elite credit card holders is not spacious enough. Noted that the free internet is available for the locals who have already had their internet IDs registered.
