I made 2 trips to SIN in the past 5 weeks. On my Jan trip, the UA agent in Business (*Gold can use the business line even for coach tickets--mine was coach E+) gave me a pass for the SATs lounge. For my recent trip, the line to check in (in Business line) took a while so there was not enough time to use the lounge. Show your *Gold card & ask for a pass to the SATs lounge.
