Yes currently under construction next to the EK lounge. From the outside of the hoardings it seems very small.The Qatar Airways Premium Lounge Singapore is set to open in early 2020.mainlymiles.com
Apparently there's also going to be a QR lounge too next year!
Anyways I'm in too
Rumour has it that Amex lounges only open for two reasons:What SIN really needs is a proper Amex Centurion lounge, like in HKG and other locations. Not that most of us will get into the private dining side of it, but I was reading a review of the Centurion lounge in HKG the other day and must say that it sounds like a very competitive offering.
