Thank you both for the Feedback,

Most likely I will go for 100k in United and 25k in NW or DL this year, hope I make it!

General you think I should go for NW miles instead of the DL miles then? I like the idea about AS, as I have a sister who lives in ANC and United just cut back service there so I would be flying sky team next time I go there anyway. The thing I have never liked about NW is they seem overly aggressive in enforcing the seatbelt fastened rule, I have been awakened before because the FA could not tell if I had mine on (I did). I think this has happened on several trips and I flew on DL last time to ANC because of it.
