Good news indeed for GVA and LX.
It seems as if LX is moving one A320 from ZRH to GVA to operate the three return flights to LHR, while one AR1 will be freed up by the reduction of services between GVA & LCY.
Any guess on which ZRH route will lose the A320? Will they pull some A320 frequencies from ZRH-GVA? Or does LX have any spare A320 (which I don't believe to be the case)?
