US Airways became an affiliate of the Oneworld Alliance today and you can now both earn and burn Dividend Miles on all Oneworld airlines.
US Airways also released the Oneworld award chart and there were no surprises. It is basically just the old award chart.
Note that you cannot mix and match Oneworld Alliance airlines with other partner airlines (mainly old Star Alliance ones).
You can access the chart on US Airways web page here.
You probably should wait a day or two before trying to book these Oneworld flights using Dividend Miles. The systems may not be synced and agents unfamiliar with the required award booking codes.
