Anyone notice lately that when you do a SDC and get put into a higher fare class that now you aren't getting the miles for that class? For example, purchased a K fare, SDC to a B fare. A month or two ago, I received 50% bonus for B fare. Last two SDC when going into a premium fare it would show on my mileage statement purchased K, flew B, and no bonus miles. Delta finally closed the loop on this?
