You know that American AAdvantage is my preferred mileage program.  And you also know that I fly Delta just enough to make that my second program.  I’ve historically accumulated my handful of Star Alliance miles into United Mileage Plus.  However, Continental’s coming entry into Star has me wondering if that’s the best thing to do.  So I’d love to hear what others think.  Should I switch my Star Alliance accumulation to Continental?  Or should I think about US Airways Dividend Miles?  Or continue with United.  Share a comment, or send me an email.
