Sure, I found that Emerald Coast was great in many ways because they taught me a lot about interview techniques and such but it was very general with the idea that the techniques work for every airline. This is sort of true but Alaska is a different animal. ATC is great in their own way too but the people that run it are getting older and it's taking a toll on them. She gets all her info from calling the chief pilot a couple times a year and writing things down and relies heavily on reports back from applicants. Rainier is actually well connected to Alaska and can help you with questions, techniques, etc in addition to truly knowing the latest at Alaska and what they are looking for. None of these would hurt but Rainier is absolutely the best option if you're only choosing one. PM me for further details if you want.
