This is seeming pretty cool actually!
Quick and easy way to search across multiple alliances. I've only been messing around with the site for a few minutes, but right away my main complaints are that you can't do multi-city award flight searches, and you can't do any sort of flexible date searches or search through a whole calendar month. It's nice to search all of the airlines, but it takes awhile to try all the different date combos to get to the cheapest award redemption.
