Are you talking about wired, or wireless? Because surely the installed terminals are still free aren't they? As of mid-December 2004, when I last visited the SQ lounge, they still were.

One additional point about the wonderful SQ lounge (where I've eaten so much I had no room for UA business-class food going back to the mainland) -- the Silver Kris Lounge opens at 15:30, so don't waste your time going over any earlier.

It's about a 10- to 15-minute walk, at a brisk pace, from the Red Carpet Club. They only let you in as a Star Gold if your departing flight is on Star Alliance, not merely your arriving flight.
