Fly about 30-35 UX segments through SFO per year and can't remember a single memorable foul moment there. Crazy gate changes and confusion on the ramp, sure, along with push problems and delays. Even with that, I've always found the SkyWest staff there pretty professional overall, compared to the mainline staff elsewhere in the terminal. In fact, I've chronicled a few stories here on FT where the UX staff at SFO have really saved me a lot of inconvenience and rectified mistakes I've made.
Have I jinxed myself?
BTW, we just flew through there today on our way home from Oz and had 3 gate changes due to cleaning crews "scrubbing the a/c parking spots" in the middle of the day
but they still got us into the conga line on time....
