My wife and I recently moved to the Washington D.C. area, and starting next week she will be flying DCA-MSY and back each week. We've been CO fliers for a long time and she does not have a DM account. It seems like the Trial Preferred program would make a lot of sense for her. The round trip is only 1940 miles according to GCM, so unless she did some MRing or connected through PHX on her way home or something like that it looks like she'd have trouble making the 22,500 or 30,000 for platinum/CP in 90 days. Gold looks doable, however. Not having a lot of experience on US, does anyone have any idea what kind of upgrade success can she expect to have as a Gold for weekday morning/evening flights? I suppose the 50% bonus miles she'd earn might make it worthwhile, too. I'm also a bit surprised that this late in the year the offer hasn't rolled over to be good through the 2012 year rather than just 2011 (Feb 2012). Anyone know if we can expect this to roll over soon and maybe should hold off? Any other thoughts? Thanks!
