Welcome to FT!
As American Airlines and US Airways continue to operate as separate carriers, with separate frequent flyer programs (for now) - though both are part of the same, merged parent company, your post has been relocated to the pre-merger American Airlines forum since one of your options involves potentially using your AAdvantage miles.
The American Airlines (consolidated) forum, for now, is being used for those issues that affect the merged operations or decisions of the parent company. Anything relating to each carrier's individual frequent flyer program or operations is being housed in the appropriate pre-merger forum.
This will all change, of course, when the carriers begin operating as a single airline with a single frequent flyer program.
Thanks for your understanding.
