After much hemming and hawing I finally decided to renew my PC membership. I fly from DTW so I've always used the NW Clubs. I really didn't want to renew without a lounge at my home airport, but I did a search on CO.com for lounges we're affiliated with. I came across Lufthansa Business Lounge, and it states on CO's page that as a Gold Star Alliance member and a President's Club member, I should gain access to this lounge. Not sure where it is, but I am wondering if anyone else has had recent access to this lounge, either at DTW or another airport, and if there was any trouble gaining entry?

I have my new PC card and my new CO Platinum card with the Gold Star Alliance logo on the front. That SHOULD be all I need, right?

Any info on these Lufthansa lounges would be greatly appreciated!
Thanks!
