The rural airport in the Palouse region is the primary air link for its two land-grant universities, Washington State University in Pullman and the University of Idaho in Moscow. In addition to scheduled service from Alaska Airlines (through its Horizon Air subsidiary), both universities use the airport for jet charters for their intercollegiate athletic teams.
