The Toronto flight with Wardair was always via BHX,so never a full load of pax from LBA on a 747.I think the subsequent operators Worldways and Odyssey also split the load.
I would love to see a Toronto flight reintroduced from LBA,now Jet2 have done the Newark flights,who knows maybe a limited series of flights to Toronto next summer.In the current economic climate I won't hold my breath though!
