Status misleading
When the "status" shows "delayed" you would think the aircraft is still at the departure airport, especially when there is still an "estimate" for the departure. The app should have a "departed" time as well so you know the arrival estimate is reasonable. In my case the app still had an estimate for departure when the aircraft was well into its flight.
