I'm posting this here because it is not really a US Air issue but rather an issue that considers the merger and I need info from both US Air and AA Elites. Here goes. Just got my Platinum US Air Elite card. I get the card courtesy of AMEX Centurion. I rarely fly US Air but have made good use of the Star Alliance Gold benefits that come with it. Along with the card came an offer to buy up to Chairman's Preferred for $899. Ordinarily, I would not consider it but the upcoming merger seems to change the calculation. If I wait until the merger is definite and buy up as late as I can, I would think my new AA top tier would also get me the systen-wide upgrades that everyone raves about - the ability to book low fare trips and upgrade. That could definitely be worth the $899 I would think! Curious to hear feedback from others about this strategy and whether or not you feel it makes sense. Many thanks!
