Where are you flying, and when?
That doesn't make sense--you can mix partners on DL awards.
Micronesia. The rules do not allow any partner but CO to be used on the 60K award and I was as shocked as you to learn that. But that's only half the problem. The main problem is CO does not release all of the segments at the same time and DL won't ticket until all segments are confirmed which will probably never happen unless I get W/L'ed on CO. Unless someone has a better suggestion.
I was planning to fly in Feb 2008 but now it'll have to be later after I can arrange for the miles.
