For a great number of years I've credited my Hertz rentals to Southwest. Before RR went through it's transformation, there were frequent double and triple credit offers which added up pretty quickly to free tickets. Mind you, I never actually fly Southwest, but these tickets were great to hand out to family members who are a lot less picky than me. With the change to Rapid Rewards, I'm not sure that's the best place to continue crediting my rentals. Finally got the first double points RR offer in some time recently, so that helps. I'm also not sure RR is NOT the best place to continue coding these points. Anyone have opinions on which conversion is most valuable for them?
