Gets the job done
I used to love, love, love this app. Now, I dont as much. Now that TripAdvisor took over - You can no longer see airport arrivals and departures, which is annoying if you cant remember a friends flight number. You can still track your flight with the number and some of the airport info is helpful, but only some. Overall it gets the job done and will get you to the right gate for your flight.
