Spanners - please forgive my naiivety here, but if Operator Y starts a direct MAN-China and CX bring forward any plans to re-commence MAN ops....won't that risk the passenger loads for either fledgeling service as it seeks to establish its' customer base. I could envisage both airlines quickly saying isn't profitable enough and we are left with no direct services again.
I wonder how much traffic is already lost to the Dubai shuttles that means new operators have a harder battle than just influencing the BA customer base who transit via LHR?
