Hi all, I am new with mileage memberships.. I started paying more attention to it in the last two years but just recently joined and started to study more about them. So, my question is, with this whole story of devaluations on both sides, UA and DL, and with me having Silver on both DL and UA, what program do you guys think offers more and better service? I live in NC, in Charlotte, a US Airways hub, which looks like it will become an AA hub soon (OneWorld, in other words). I have plans to fly more next year and would like to have some advice or tips about where I should focus on. I am asking this based on both, my location and the mileage program.
