There would be plenty of time as they were doing 4 LCY rotations with the one aircraft ( although with later finish time) up to the start of last winter although I cannot see why anyone would want to take on EZY on the relative;y thin Belfast routes.
I just hope Loganair can run the service punctually and reliably although it is a pity BACityflyer did not decide to use their own metal on the service and give EZY a bit more competition on the London routes
