Hi, newbie to the forum - have searched previous posts and come up empty.

Can anyone tell me if Lufthansa offers or allows status match or status challenge? I'm an American expat living in Cologne, Germany and I have Diamond Medallion status with Delta. I've been at this level for 3 years due mostly to tons of frequent business travel but living in Germany it only makes sense to fly Lufthansa, and/or their lower-cost affiliate GermanWings.

I'd really like to leverage my Delta frequent flyer status to get Gold or Senator status on Lufthansa, thanks in advance for any help you can offer!
