MQMs - if I fly on other skyteam domestic partners (CO/NW), does the flight have to be codeshared with Delta to receive MQMs? Or can I just book a flight thru them and give them my skymiles #?</font>
The correct answer is that you can do both.
Please note (using the link provided below) that there are two different types of Medallion Qualification Mile charts: one each for Continental Airlines and Northwest Airlines flights with no Delta code-share involved, and one for Delta code-share flights on either Continental Airlines or Northwest Airlines.
Here is more information.
