From the Lawrence Daily Journal-World for Nov. 19, 1972:

The new Kansas City International Airport was experiencing a little turbulence, with several services not yet fully in place. One of the biggest problems was the lack of signs directing passengers to transportation downtown. Many telephones for limousine and taxi service had yet to be installed and limousine service booths were not yet open. Five buses and five limousines were making 49 scheduled trips each day from KCI to downtown, but passengers were able to board buses only if they could find the correct bus stops.
