Will be flying the return to SFO back home from my honeymoon in April. Lowest fare bucket right now is S. Plan on paying ~$90 more per person to book into W. A GS friend is going to use some of his new PlusPoints and get us on the upgrade wait-list. Figure the higher fare class and half the Points is worth the higher cost.
(Using hidden city and adding a domestic leg after SFO brings the cost down a bunch, but I've already used the trick once in the past 12-months and my fiancee has asked me not to do it again...)
