I have an interesting dilemma. I purchased a multi-city flight through United.com, which included 1 United segment and 2 Alaska Airlines segments. Since I purchased it through United.com, I feel like I should be getting the mileage and PMDs for the Alaskan segments, but I doubt this will be the case. Does anyone have any information they can impart to me?

(I bought through United because it was actually cheaper than other websites, believe it or not.)
