As you say though, travelling in F on UA isn't a hardship and if I wanted to get to LAS, then I'd happily do it. I would personally try to get NZ (J), LH (J), LX (J or F) ahead of UA.
I'd sooner do LH in F myself these days, but at the end of the day, I'd rather have the experience of SFO at the other end (UA also has an arrivals lounge there too by the way) over LAX any time.
