I noticed the MQDs on a partner flight purchased through AmEx travel with Membership Rewards posted as $0 (the mileage did post).

When I called to inquire, I was told the partner travel was not eligible for MQDs because it was purchased through AmEx rather than Delta.

I thought that effective January 1, 2015 partner flights not ticketed through Delta were eligible to earn MQDs based on the fare class and miles flown. Did the agent give me the wrong information, or is AmEx MR an exception?
