Does hipmunk do anything different? It doesn't look like it can tap into sabre, ryan air db, etc, looks like it just scrapes and organizes, nor does it look like it has any fancy back end db of extensive flight info with a smart heuristics engine to predict future prices. So, beyond help those who have trouble visualizing a schedule, I'm not sure how this is any better than farecast et all. Can hipmunk predict if a particular flight's price (not willy nilly flights, I'm looking at you farecast) will go up or down?
