Interesting-- before seeing your post I was already planning on asking how Hipmunk is better than Kayak, if at all... EDIT: Okay, I tried Hipmunk for an upcoming flight. Pros: It offers a 30 day window for a flexible date search as opposed just 7 days on Kayak. Pretty interface. Cons: Far fewer search options. My fare was $150 cheaper on Kayak! (Chicago to Hawaii over New Years).
