I have enjoyed being DM for the last 3 years (my wife enjoys as well). Specially being based in ATL. The UG are hard to come by but it helps when you plan non peak hours. The GUCs are probably the best thing about DM. Last year we saved thousands of dollars by using the GUCs with KLM and visiting Asia.
Now that Corona Virus is hitting Asia, I may not be able to reach DM since I go to Japan for business a lot. I wonder if I can apply "Reclaim my status" hmmmm…….
