I've recently noticed that Delta SkyMiles have nowhere near the value they used to have—a round trip Delta One flight to Asia can cost upwards of 600,000 miles, whereas through American/Alaskan, I've only seen up to 150,000. I can't even redeem SkyMiles for Korean Air flights anymore! I was wondering what are good alternatives to the SkyMiles program, or even just a program that is a partner with Delta. I've looked at Virgin Flying Club (which has outrageous fees and scarce award availability), and have heard some good things about AF/KLM.
