I love Hipmunk except for that it only gives me limited options for purchasing at the end. I'm guessing this is to maximize their referral revenue, but I have status on an airline and only purchase from their site directly. If I purchase from another site I have less control over changes to my itinerary after purchase. That's my preferred airlines fault, but other sites like Bing Travel let me click through the results right to my airlines' web site.
