I just got an email from Hans G regarding the above that you can see live at Delta.com HERE
Now I am sorry if your heart skipped a beat when you saw this list and the fare classes. The key thing is this will not affect most of us. There will be a few rare times you will want to check up on this and I hope to have Tamara do a post on this soon so stay tuned.
I have also contacted Delta and this will NOT affect fares that are booked with “published fares” i.e. anything you book at Delta.com! Even a “mistake fares” will get FULL credit. Again, if you book it on Delta.com you get full credit.
Also safe are things from Delta Vacations and government, military, corporate, sports and university fares.
So all is not lost for us who like a mileage run now and then to keep our status with our beloved airline! – René
