Experience from BA 961 MUC-LHR yesterday night: first time I've noticed "an attempt" at group boarding in Munich (I usually go there once a week). No lanes or any equipment to close off / open areas by the gate B 03), likely due to space constraints. Boarding was delayed due to snow so quite a large crowd was waiting in front and near the gate already. Announcement of group boarding by gate staff, quite a lot of people rushed forward when Group 1 was called. Grouping was enforced partially, i.e. they briefly looked at every 5th-10th persons BP. It felt like an unusually high number of Group 1 passengers just from glancing at boarding passes and the fact that there were 5/6 rows of CE on the plane but nevertheless it is good to see that they're trying to implement it in MUC as well...in previous weeks it simply was the old style CE/Gold/Silver/Bronze first and then everyone else
