Search on codeshared flights didn't turn up the answer that I wanted. I booked a flight for the following cities:

CVG-DTW-SEA (H-class in CO) (NW-operated)
SEA-IAH-SAT (Q-class in CO) (CO-operated)
SAT-IAH (I-class in CO) (CO-operated)

I realize that all of my CO flights will earn 50% EQM. However, the H-class should earn 150% EQM, theoretically. Looking at my itin on nwa.com, the booking class comes up as M-class on NW earning 100% EQM.

Will it be 100% or 150%?

Thanks.
