The Inchoen airport in South Korea opened in 2001.  It's relatively new.

The Honolulu airport, where's it's located today, first opened in 1962, with the Diamond Head concourse added in 1970, the Ewa Concourse in 1972, and the central Concourse in 1980.  https://en.wikipedia.org/wiki/Daniel_K._Inouye_International_Airport

In other words, HNL is old.

However, in my opinion, it's better than some terminals in Philadelphia, Houston, Newark, London (UK), Washington, D.C., Dallas, Toronto, Narita, and some others I can picture in my mind, but can't remember the names.  Essentially, most airports are old and in a constant state of modernization.
