And what jetport did Hawaii have in 1961?

Per Wiki: "In 1959, Qantas began the first jet service to Honolulu as a stop on its flights between Australia and California."

I'm not sure what you mean by "Jetport", but if the runways are long enough and able to support the aircraft weight then you could call it a jetport. Remember that there were no jetways back then, stairs were towed out to the aircraft and the passengers disembarked onto the tarmac. After all, Honolulu was a stopping off point for trans-pacific flights for a long time prior to the advent of jet service.
