Follow-up.
18:00 departure scheduled for 20:00, somehow avoiding the returning aircraft getting caught in the FRA 23:00 curfew??
18:15 departure moved to 18:35 (because turning an inbound MUC aircraft around). Departure boards go quickly from "Go To Gate" to "Gate Closing", so panicing pax running to the gate
19:05 Ground handler is advising the gate agent that departure will be 19:30, and to be ready for boarding
19:10 Departure boards in the terminal change to "Cancelled", which the gate agent didn't know about.
Really not a strong performance.
