This year I was living in Houston and flew out of IAH all the time, got Gold with StarAlliance and United but won't quite make it to Platinum. My miles are all with United. Now I've moved to MSP, which is a Delta hub, but oddly the last couple of business trips have been half the price on US Airways than they were on Delta, and Delta have been useless at following through with any kind of status match offer, despite my emailing them three times and calling them once. So frankly, I'm not even inclined to give them my business at this point. I book my flights with my Corporate AmEx card for the double points, and when I book with US Airways I still get miles, bonus miles (for my Gold status), and segment credit, along with Zone 1 boarding access, free bag, priority luggage and priority at security. All good. The problem is AmEx don't seem to have a good method of tracking my flight status. US Airways show no record of my flight, because I signed up for it with my United number in order to get proper credit. What's worse is I can't pick or change seats until I get to the airport as US Airways don't see me as elite at all (on their web site). I don't think airlines like to do status match between airlines in the same network. So I was hoping for some good suggestions as to how to address this conundrum. I want to continue to take advantage of all my elite benefits, and ensure I maintain them for 2014. But I'd really like to be able to track my reservations via my iPhone, and be notified of delays etc.
