MUC-LAX-FRA C class. The seat is unconfortable in the flat position but okay in the other ones. Amenity kits were different both ways and very basic. No amenities in the toilettes. AVOD system is working but a bit complicated and selection of movies also basic. The meal, nothing special to talk about for a business class. The service, though it is up to the mood of the staff in that particular day, was efficient - but that's it. On disembarking, on both ways (LAX and FRA) the C and F class were beyond all others passengers due to only one door open, but none of the cabin crew seemed to care. The money you pay for a C seat is not worth it
