Continental Airline Tickets

Can I use my NWA Worldperks miles on US Airways flights?

I know some airlines will let you use your frequent flyer miles on other airlines for a higher price. Does anyone know if you can use Northwest Worldperks miles on US Airways flights?

1. No they are not interchangeable. NWA does offer with other carriers, but not USAir. http://www.nwa.com/worldperks/redeemmiles/fltawards/ This site shows what carriers they partner with.
2. You cannot use NWA miles on US Airways flights. They are not part of the same alliance. You can use NWA miles on Delta or Continental Airlines. US Airways and United Airlines are in the same alliance and you can use United Airlines miles for a US Airways flight.
