My question is, when banking miles, should I bank into UA or US? Which one has better reciprocal benefits via Star Alliance when traveling on the other? Are they exactly the same when it comes to that aspect (aside from the merits of each program v. the other)? Does it even matter if I'm not at least Star Gold one way or the other?
