Review by CHC
As a delegate part of a conference group enroute to BKK, I opted for a walk in upgrade on TG for S$185 to Business class from my Q category ticket so as to be able to review the TG lounge as well as the new A350-900 to BKK.
The Lounge is located in a quiet spot of Terminal One near the central immigration on level 3. There are a few lounges close by like the SATS (which is accessible via the Priority Pass card) and Qantas lounge.
