I'm a recent convert to the world of miles and status but am certainly doing my best to catch up with both! Having gotten the BA credit card miles plus cashed is some AMEX points, I'm planning on taking my SO somewhere in the world sometime in 2012. (We have 300K BA miles and will rack up enough spend on the card to get the companion award ticket, too.) In September - November, I know I need to do at least three (and possibly six) transcon flights from SFO-WAS, and can do so in business class. Is it worthwhile to do these flights on American as part of a Platinum Challenge? SFO isn't an AA hub, but if we're going to use the BA miles for our big trip in 2012, I'm thinking the status might make our lives easier on the other OneWorld carriers. Are the rewards worth the effort? Or should I use those transcons to rack up miles with another carrier who uses SFO as a hub? Any tips or advice welcome.
