Well, you are in luck....that is, if you do not mind traveling on board an aircraft that is not a jet. There are two airlines serving Sun Valley at this time. The first airline operates nonstop flights into SUN from Boise and Salt Lake City and operates three different aircraft types on these routes. The second airline only operates nonstop from Salt Lake City and only operates one aircraft type on this route. Identify both air carriers and the respective equipment they were operating into Sun Valley at this time. Both airlines were commuter air carriers, one of which went out of business fairly quickly. The other airline reinvented itself some years later which included a slight modification to its name and then started flying jets in scheduled service from a hub that was not located anywhere near Sun Valley.
