That's a great deal for MKE passengers...does it go the other way?
Obviously, NW would be the better club to buy...now it gives you NW, DL, CO and YX access in the US. Makes it nice for those of us that split our flying between NWA for international and certain domestic, and YX for direct flights (not on CRJs!).
Very tempting...still haven't done it, but have always wanted to. Spent 6 hours in the FLL PC over the weekend thanks to an NWA bump (to YX no less), and enjoyed it thoroughly. You don't realize how much more productive you can be with a comfortable chair, few overhead announcements, and easy access to free refreshment (I enjoyed the Amber Bock). Now the problem is, NWA's connections through DTW and to a lesser extent MSP (not true of MEM ever in my experience) are too convenient! I almost always have 50 minutes in DTW and less than 1.5h in MSP...certainly doesn't make the WC worth it!
