Been to both lounges, UA RCC is huge, including a seperate bar area. Staff at the desk were very friendly last time I was there, but probably because hardly anyone was there. The drink and snacks are very mediocre.

The SQ KF lounge in comparison is considerably smaller. I was flying out on UA on an evening flight from SFO-SYD, and the SQ KF lounge didn't open till about 1 1/2 hrs before the flight. It was empty, and has 2 sections, first and others. It accepted my *G card for entrance, no probs at all.

As stated, empty internet PC is there, and a shower (which was excellent!! - I needed it, the UA RCC folks said they didn't have a shower). They also have nice food and snacks at the KF lounge - hot chicken wings, dim sims, sandwiches, cheeses, biscuits, etc. Plus plenty of booze. There are windows to look out of. It can hold about 30 folks in the area I was in. I definitely recommend the SQ lounge but other than that, the SFO international airside area is VERY boring and would not recommend going through till about 90 mins b4 your flight ...
