From the Lawrence Daily Journal-World for Nov. 9, 1972:

With the departure of a Delta Airlines passenger carrier for Memphis, service at the 5,000-acre Kansas City International airport was scheduled to be inaugurated at 1:20 a.m. this coming Saturday. The first scheduled arrival at the airport, which had been dedicated three weeks ago by Vice President Spiro T. Agnew, was to be a Frontier Airlines flight from Denver at 1:34 a.m. Staff for the eight airlines served by KCI had been busy moving office equipment from downtown Kansas City locations and from the Municipal Air Terminal to the new airport 20 miles to the northwest. KCI, boasting a north-south runway 10,800 feet long and an east-west runway of 9,500 feet, had been serving since 1956 as the main overhaul base and technical services center for Trans World Airlines (TWA).
