Just got this email, not sure if this is old news or not, thought I'll share.
Dear xxxx,
As part of our continued partnership with American Airlines, we are pleased to announce that ExpertFlyer now supports full US Airways Award & Upgrade searching and alerting. The addition of awards and upgrades from US Airways operated flights will complement the existing American Airlines operated award/upgrade data already available to subscribers of ExpertFlyer. In addition Flight Alerts can now be created for award and upgrade inventory for US Airways operated flights.
