Destination information is taken from Atlantic Gulf system timetables as well as from Official Airline Guide (OAG) flight schedules.
According to the February 1, 1976 edition of the North American Official Airline Guide (OAG), Sun Valley Key Airlines was operating scheduled passenger flights as a commuter air carrier from Salt Lake City (SLC) to a number of destinations in California, Colorado, Idaho, Nevada and Utah.
The OAG business dates back to 1853 when it first published the ABC Alphabetical Railway Guide, later to inspire Agatha Christie’s novel The ABC Murders.
