HHonors' Miles and Points can be useful if your want to maximize earnings through partner promotions, but ultimately I want to transfer those miles back to HHonors at a favorable rate. Amtrak GR works pretty well without a promo, since 500 fixed miles yield 500 Amtrak points and then 1,000 HHonors points - assuming you meet Amtrak's criteria for transferring points out. What are the other winners - did I hear Virgin Flying Club? How many Virgin miles do you earn with 500 fixed miles from HHonors, and how many HHonors points is that when transferred back? The current 1K points promo could make this favorable. Any other contenders?
