I have now had the chance to sample BA's domestic South Terminal product. I was favourably impressed by the check-in/bag drop area and the Club/Exec Lounge but at least on the flight I was on there was a problem processing pax at the gate as only one security agent (and one machine) to check the boarding card photo. This led to a queue from gate 12 down the centre pier, about 100 yards long. Also not impressed that all domestic arrivals are coached.
