Went out of Manchester yesterday with Jet 2 from the old Pier C. It was like an obstacle course up and down stairs and none working lifts / travelators, ye gods it was not a good experience as a passenger. Not had those issues with LH or Emirates - just a long walk usually with EK.
It is quiet, why can not things be fixed while they have the opportunity. I know ultimately it will be pulled down, but you can not just abandon maintenance until the replacement arrives !!
