What would be the logic of splitting a load LBA - MAN - YYZ,
what would any airline gain by half filling a 757, start up, taxy, take off for a 15 min flight, land taxy, finish loading, fuel, taxy, take off again !, x2 landing fees and loads of fuel burnt.
It would be cheaper for the airline to pay for taxis for Yorkshire PAX to drive the 40 mins over the M62 to MAN.
