It will return to Airport once the Airport is back up and fully functioning or at least at a level that requires a service.
All operators do ,the airport basically auction of the stances they have when the tender expires .
Or they could put bus stops on Howden West Road with a new pedestrian crossing for the side with Coop on it and operators could alter if required to use Eagle Brae and Burnbank to allow services to continue in correct direction , there is ample room to facilitate this if as they claim Hospital grounds cant cope with the public transport numbers using it.
What they cannot do is allow 1 or 2 operators carte blanche and exclude who they choose ,surely.
I used to live round the corner and believe me, it isn't the first time I have witnessed a traffic jam where a taxi or multiple parked cars picking up outside the main entrance have made buses and the rest back up and block the entrance into the Ambulance bay, that bit of road was poorly designed when I lived there, don't know if it has been improved in the last 5 years, having buses go elsewhere would be the start of a good option or maybe an entrance/exit across from St Margarets with a bus stop at the rear of the hospital in a one way system would work, that side of the hospital is staff only IIRC and usually pretty empty for the amount of car parking space there is there.
