There are no zero stars, but thats what I would rate it. First, it doesnt seem to work in airports. You cant get updates on gates or flight times. Second, it logs you out continually, which is annoying. Third, if you want to check into a flight on a partner air line you are out of luck. It sends a check in notification, but does not allow it. There is a lot of things this app could do - update flight info, let you know about delays and connecting flights. This app does none of these which is aggravating. You are better off to stick with the board at the airport if you want current information about your flight.
