How is this Kayak tool better than FareCompare? Is it better because it shows "possible" fares against a map, so one can focus on cities of interest to them? But for a FTer in search of a good MR opportunity, the destination city is a matter of indifference, isn't it, since it is all about airline, scheduling, and cpm? FareCompare has that filter function that allows one to focus on the hugely important detail of airline and/or alliance and the all-important cpm with taxes and fees included.
