So there really are no other benefits then what is listed on the website? That seems like a pretty bare bones elite programme. It doesn't really get you anything beyond what *Gold does- ie. it doesn't seem like I'd be any better off as a Krisflyer Gold flying SQ then I would be as an AC Elite. And I've been to the Krisflyer Gold lounge at SIN and been none too impressed... I'd rather spend the time in the airport. I guess they reserve all the real benefits for PPS?
Take a look at SQ*S, if you think *G is bad
Bare minimum benefits promised by *A (priority standby & waitlist), nothing more. Even flying as SQ*S on UA gets you more than flying on SQ.
