How did you access the Airport Lounge World in MUC? When I tried on 8 December 2018, my DM / Skyteam Elite Plus status was declined (the Delta web site at the time, and Delta's twitter representative, indicated that I would have access).

Also, the remote gate C25 provided some excitement, where the jet bridge backed up but the escalator continued to deposit passengers. Several people tripped, and an elderly individual being assisted to the plane nearly had a very bad accident. There's a panic button or pull at the top of the escalator, which someone eventually had the presence of mind to activate.
