I have a similar query. Basically I plan on matching my status to Alaska for an upcoming trip to the US. However, another option is to get a delta challenge and based on my flights already booked, could qualify for elite status. However, I've read conflicting things about delta and possible future changes so am unsure if it might be better to concentrate miles collection with Alaska or not. To give you info about my situation, I'm living in Ireland, planning a couple of months travel for next year. After that, i won't be flying very regularly but will have occasional trip Europe-us and intra-Europe. Can anyone offer insight as to whether I'm better of using alaska for miles Collection/future awards or would delta suit my situation better?

Thanks all
