I had understood the intention was for most of the A333 fleet to end up at MAN to operate the growing network there.
That was on the assumption that the fleet could perform route sectors like MAN-SFO/LAX (realistically the longest sectors they would operate).
Perhaps if they only have two A333 in the fleet that can make it to the west coast, the frequency will be limited to 4x weekly (not unreasonable) but I don't see how the A333 would have the capacity to operate MAN-MCO.
