I would agree with Swaggie. It took me about a month last August to receive the comp to Gold from Northwest, but the actual notification letter came a month after that.

If you have your Northwest Worldperks number, check your mileage balance on the website. It's possible they've granted your request but haven't gotten around to notifying you yet.

I too am waiting for a reply to a request to keep my Gold comp since I "started so late" and didn't have that much time 4 months to re-earn it.
