Its probably too early in the game ...
Really? Given that DL/NW, CO, AA and UA and US have all done EQM promos? Basically, AS is the only big traditional carrier who hasn't (thus excluding WN and B6).
Now granted, if their elite yields are doing fine, it wouldn't be necessary... but I'd argue it's getting late in the game, if anything, and it might be tempting to defect to CO if you fly a lot of ANC-SEA and are noticing CO offering DEQM AND lower prices...
