Since Delta will, hopefully, soon be giving us the ability to redeem miles online for mileage upgrades, I have the following question:

- If you were to use miles to upgrade on either a domestic or international itinerary, do you still earn miles for the purchased portion (i.e. the coach ticket that you bought)? If so, are those miles still counted as MQM?

If the answers to both these questions are "yes", I REALLY look forward to booking these mileage upgrades online. And honestly, I feel I would spend more on coach tickets to make sure they are in the proper fare class in order to use miles.
