We did end up going through MUC. We had not checked any bags. All I can say about MUC is WOW! What a clean efficient airport. The Germans really have a jewel of an airport. We had no problem whatsoever going from one terminal to another.
I cannot say enough good things about LH. 24 hrs prior to departure I received an email from LH stated I could check in. I did thinking I would have airport standby listed only. They went ahead and assigned our seats! It really was nice not to have to worry if we were going to get on the flight. We will do it again if we ever need to. MUC is a good back up.FCO on the other hand is another story. I hope this information might help anyone looking for alternate airports to nonrev through.
