只能自问自答了:
But one interesting feature of the Delta Reserve card is the ability to “gift” those bonus MQMs to another person. You’ll find this option listed in the Benefit Terms of the Delta Reserve card. Take a look at this zoomed-in section and the sentence I’ve highlighted…
Note that this option to gift bonus MQMs does NOT exist for the Platinum Delta SkyMiles Credit Card — only for the Delta Reserve card. So don’t apply for the wrong card if you’re hoping to give someone else your MQMs.
