The blog Free Frequent Flyer miles noted last week that Korean Airlines does not charge a fuel surcharge when you use their points to redeem on Alaska Airlines or Hawaiian Airlines. This is noteworthy because Korean only requires 20k/40k for a domestic coach/first class roundtrip on Alaska (stopover permitted); and they only require 30k/60k for a roundtrip to Hawaii from the mainland (inter-island flights, though, are charged separately at 10k roundtrip). (FFM says to redeem you should call 800-438-5000, and then prompts 2, 4, and 0).
Why do I mention this? Because Chase Ultimate Rewards points can be transferred into Korean Airlines, one of their partners I tend to forget about. But for those Alaska and Hawaiian awards, they can be a good deal.
Since I had forgotten about those partners, I thought it would be helpful if I compiled the full list of airlines you can fly on using Ultimate Rewards — in other words, all of the partners of the partners.
