I recently had flights posted to my account that had been upgraded to first class. They posted, under "Class Flown/Paid", R/K and R/T. The flights DID post as an EQM Segment credit.

I was under the impression that the only paid classes that qualified for segments were P,F,J,C,Z,Y and B. Am I missing something? Don't get me wrong--I'm glad the have the segments posted to my account, but I didn't think that class K and T qualified.
