U, Y, S, B, M, H, Q, L, V, K, G, T class fares on Alaska earn 100% EQM. You receive a minimum of 500 miles per segment, and the entire 500 miles counts toward elite status. As long as your fare class falls in those listed above, you will receive 100% of 500 miles per segment with a total of 1000 EQM for the round trip.

I see you are flying SNA-OAK-SNA, so you must be flying Alaska metal. That will be fine. Keep in mind Alaska codeshares operated by AA do not accrue CO OP miles (and IIRC, those are R class fares).

Happy flying!
