I'm fairly new to the miles/points game, and traded around 17k US Air miles for 3k on VX. Beginner's mistake. I am still bitter about this exchange. Avoid points.com like the plague. Their exchange ratios are a travesty. On a happier note, this is the only points transaction I regret. Thanks to the knowledge available here and on FT, I've learned quickly and have not repeated such poor decisions. In fact, so far as I can tell, since then, I've made nothing but good (great?) decisions re: earning miles! And I have no one but the knowledgeable posters here, and on FT, to thank for helping me learn quickly. Thank You!
