Does Flightaware provide info for each flight, say, if it deviates from course it will be longer than usual?
No airline provides credit for, or informs passengers of, "actual" miles flown, to include flight path changes, "go arounds", etc. They each use a standard (for that carrier) distance calculated point-to-point between two given airports.
