Better F: LH or F (and how can you tell if LH flight is New F)?
What are the differences between LX and LH in F?
Food (both do both have caviar?), champagne (Dom Perignon?)/wine, seats, IFE, ZRH vs FRA lounges, etc.
Also, how can I tell is MUC-BOS tomorrow on LH 424 (A346) is New First or Old First?
