I'm flying LAX to MUC tomorrow (Wed 29th) and I've been monitoring business class availability on expertflyer which used to be very good with 9+ seats available. All of a sudden, it went to zero. I suspect that Lufthansa planned to use the upgraded A380 on that route which has fewer business class seats since the new seat model takes more space.

Could that be? And if yes, is there a tool that can already tell me right now which exact plane registration is planned to be used for tomorrow's flight?
