Quote: "Lets hope BA don't let Leeds down. They have a habit of cancelling domestic services when things go wrong on the network. Their flights to Manchester have had a bad track record during the winter."
Good point, crewmeal, suspect that has much to do with LHR operating at 99% capacity on a good day and the fact that there is no slack in the system. Under such circumstances, short haul services are usually more vulnerable to cancellation.
