It's a cool in a geeky sense that destinations drop off the map when I click back and forth. How does this solve my problem as a customer though? I know I need to get from A to B. How does the map help me choose which flight from which carrier on what day?
True. The UI however is something else. Really gets out of the way and gives you what you are looking for. Feels effortless to use compared to the usual suspects in this domain, IMHO.
