However, since Taiwan government practice the “Open Air” Policy at the end of 1987, new airlines and airline companies increases one after another, so the civil aviation business develop rapidly. Meanwhile, the Taiwan government's opening up of the mainland China visiting to citizens and the more and more serious Land traffic in Taiwan makes the business growing rate up to 30%. In order to handle the growing business in the future, the CAA again draft the expanding plan, and build five more Apron Parking lots and one main runway at the year of 1986 and 1987. The Phase II of expanding plan starts on January 1991. Among them, the International Terminal building is finished and start using on January 11th, 1997, and the Cargo plane shed, car parking lots, overpass, pedestrian bridge, and maintenance shed are already finished.

The Domestic Terminal Building, Control Tower, and other equipments for guiding navigation are finished on May, 1972. It has gone through some constructions and then become what it is today. KHH Airport is now the first International Airport which runs two Terminal Building, Domestic and International airlines, in Taiwan. The finish and opening of new International Terminal Building improves the equipments a lot. The Domestic Terminal Building is now on the pre-preparation procedure of dismantling for rebuild.
