Okay, let me ask you a question.
1. assume you are NW WP Gold
2. you fly 25K miles on CO and 25K miles on NW during a calendar year
What are you the next year? NW WP Silver? Or do the actual flight miles "pool" to make you NW WP Gold the next year?
Thanks for clearing this up!</font>
They only pool if you use 1 account, ie you should only use a WP or OP account, but not both.
The nice thing about NW/CO is they treat each others flights as if they were their own flights for frequent flyer credit and give full benefits to the other programs members as well.
