Can someone give me some examples where this tool works out well? I live in a hub city (MIA) so I can't seem to find any results in their search (or is their site overloaded?)
Not sure about the tool specifically, but I know that tickets to Charlotte/Atlanta from MIA/FLL are often more expensive than tickets to New York from MIA/FLL, routes which almost always have a layover in Atlanta or Charlotte.
Same. Can't seem to find many flights from a major hub city (ORD). I've just been flipping in new airport codes into the custom URL[1], but haven't gotten anything yet.
