Advice for SFO-SYD:
My wife and I are using pluspoints for an upcoming trip applying them to a B fare as 1K travelers. Another couple now wants to join us. Not sure how to advise them; buy the B fare and wait until a few days before the flight for a paid upgrade, or to pay the $600 plus the MUA (30K) on an L fare today. Not sure where both of us will be on the waitlist.
