On March 31, US Airways is leaving Star Alliance and joining the oneworld alliance.
The good news is that you will still be able to redeem US Airways miles on some Star Alliance carriers:
- South African Airways
- Turkish Airways
- Air New Zealand
- and many others
The bad news is that the US Airways and American Airlines mileage programs will operate separately so you will not be able to merge your miles in the two programs until sometime in 2015.
