 SAS announced in September 1988 that it intended to change this model.DC-9s and MD-80s would fly nonstop from Oslo to Alta, and then a hub and spoke system would be established by SAS Commuter whereby they would feed into the Alta, which was designated as hub.This led to increase frequency on some of the feeder routes, for instance from three to six on the Tromsø to Alta service and Kirkenes going from two to five daily services.
