As far as I can tell this app is no different from others in terms of flight status and airport delays. So if it has no advantage in this area then it must have insight into airports that actually makes travel easier. The tips for airports are people whining because their flight was delayed which is not really helpful to anyone but the unfortunate people who used it as a therapy session. I guess I will do what I always do when technology fails I will talk to a human in the airport and ask where the best food is located or the car rental bus is.
