I thought the old lounge was sub-F standard, but presumably BA know this lounge changer - but on my MMB info it still has the old info
Lounges
Qantas/British Airways First Class Lounge
Location: After immigration, follow signs for airline lounges on upper level. Escalator to the left. (Lounge access is subject to capacity restrictions.)
FIRST lounges offer an environment that allows you to catch up on work or simply unwind in an area that is elegant, calm and welcoming.
I wonder when they'll update the website and whether there are any better options at SIN ie OW Saphire / PP or other?
