THe new C is not consistent on the YYZ-FRA route. It was here for a while, then they switched the plane out for a different route. Last summer a 747 took over the route, and LH has that in their schedule again for this summer.
Right now the C class is the old style. Don't even know who to call to find out if the new or old (fyi I was told new for my last journey but we ended up with old

)
