I'm trying to get an upgrde award on CO using NW mile (ewr - sin). Talk to the agent today and was told that if I buy ticket from CO. I would have to use 25k for ewr - nrt. And additional 15k from nrt-sin since it's a codeshare flight. Is this true? Does CO have availability website like NW (wpaa list)?
thank you
