No that looks correct at first glance. You get 5x dollars as base miles and 6x as bonus for a total of 11x. Looks like your base fare was $309. 309 * 11 = 3399.
You can verify that the miles posted by fare instead of distance, you should see "Method: Fare" or "Method: Distance" on the detail screen in your history. Partner flights or trips where AA IT loses the fare info usually post by distance instead of by fare.
