The South stands aren't exactly ideal though are they? Not yet anyway until they extend a pier that far south. Its a lot of bussing around to the main terminal; one of the masterplan's cornerstones is to increase the number of contact stands. (I also don't understand why the airport hasn't put at least 6 airbridges on Pier A and plan more on the proposed Pier B).
Thomson and Monarch for instance may want to make use of their Boeing Goldcare arrangements by doing heavy B787 maintenance in H60, H127 and H61 rather than at some of their outstations.
