It depends on how the bilateral actually works.
Would the CMB-LGW-YYZ-LGW-CMB be counted as 1 frequency, or will it be 2 frequencies based on CMB-LGW-YYZ (1) then YYZ-LGW-CMB (2)?
Id expect another frequency on LHR to make it 14 weekly, and thus double daily, then 4 for LGW (I think thats what the CEO wanted), then possibly 2 for MAN? Id expect 2 a week direct to CMB would be more than adiquate for MAN, given the smallest aircraft they could use would be the A332.
