My wife and I are redeeming United miles for a IAD-FRA-MUC-SIN itinerary in First Class (IAD-FRA on United, the balance on LH). Presently we have a long (8 hour) layover in Frankfurt where I look forward to enjoying the FCT. We arrive in MUC only an hour before our flight to SIN. My question is, should we maximize our time in FRA or get to MUC earlier. My assumption is that as a first class passenger FRA is a better place to spend such a layover. Am I correct? Thanks!
