I should certainly hope it's worth it. I am flying on a companion ticket in F LHR-DXB-SIN-BNE SYD-DXB-LHR next Feb. I will get to sample both the 77W and the 345 (how much am I looking forward to those suites!!)
My original plan was to fly J class with either BA/CX/SQ but the travel agent said for the same price we could fly F with Emirates. Seems like a no brainer to me, especially when you factor in the free chauffeur at each destination point, the quality of the food, the ICE...etc.
