I am trying to decide whether to credit some upcoming AA flights to AAdvantage or Alaska Mileage Plan (or USAir Dividend Miles, in the next few weeks, I guess). I have no AA or AS status, and I'm eyeing Alaska's status as being perhaps a better long-term choice than AAdvantage, assuming I won't get EXP on AA. I am having a great deal of trouble predicting my travel patterns for the rest of the year - I might or might not get enough miles for status, depending on how things go. And if it looks like I'll definitely be flying more on AA and/or AS, I am happy to do a match (or AA challenge), but I just don't have enough certainty about plans right now. Other bits: I am Boston-based at the moment. I have a sizable stock of AA+US miles. I am not averse to branching out - AS seems to have a generous program. I think my lifetime miles will be ~.5 M after the merger, and lifetime status seems out of reach right now. I also have UA Gold (their 50k tier, from being a million miler), but my loyalty to them is waning. Something about a gutting of the earnings from paid tickets. Have any advice for me?
