Be nice to see a dedicated lounge in SFO, one with showers as the United RCC doesn't. I prefer to use SFO over LAX for my entry and exit point into the US, as it's less crowded and I've had better luck on PE to BP upgrades out of SFO. But without a shower in the northern summer, it's via LAX for me.
Showers in the Auckland are good (used it this morning on my LAX-AKL-MEL flight), hope they don't reduce the size (or take them out together).
