Ok, thanks for the clarification. I now understand, although the Delta website is misleading and Delta also makes it very difficult to find the disclose terms and conditions.

Listed below are the terms. To transfer MQM miles they must be AMEX MQM miles earned from spending on the AMEX card. You also must contact Detla within 90 days of when AMEX awards the miles to transfer them.

Terms & Conditions
All SkyMiles program rules apply. To review the rules, please visit www.delta.com/memberguide. The close of the calendar year is December 31, without regard to the time of the year that the account is opened. If in any calendar year your Eligible Spending on your Delta Reserve Card is $30,000 or more, you will be awarded 15,000 Bonus Miles and 15,000 Medallion Qualification Miles (MQMs). The 15,000 MQMs are not redeemable and only count toward Medallion status. The MQMs are yours to keep or gift to someone else, and if in that same calendar year your Eligible Spending on your Delta Reserve Card is $60,000 or more, you will be awarded 15,000 Bonus Miles and 15,000 MQMs. The MQMs are yours to keep or gift to someone else. MQM gift recipients must have a valid SkyMiles account. If within 90 days, you do not elect to designate an MQM recipient, the MQMs will be deposited in your SkyMiles account. You may be permitted to have more than one Options, Classic, Gold, Platinum, or Delta Reserve Card from American Express account; however, you are only eligible to receive one annual bonus for each type (i.e. Options, Classic, Gold, Platinum, or Delta Reserve) of Delta SkyMiles Credit Card account from American Express.
