Im not doubting Zurich's yield capability, its just, its obviously seen as a marginal route as Zurich has also been in the CX game of 'maybe, maybe', so to go straight in at daily seemed a little high. I would have expected something like the 4 weekly MAN flights.
The question is though, will the MAN cargo flights continue? I suppose they may carry outsized cargo to MAN to justify the B747's, and keeping the 3 weekly Cargo could effectively be MAN's form of daily CX flights. (3/4 split)
