No one's mentioned Kona, Hawaii, yet.
Kona has an 11,000 foot runway and an international terminal, is served by AA
, JAL, and of course AQ
. But the town of Kailua-Kona itself is quite small, less than 30,000 people if I recall correctly.
the only reason it's so busy is because it's Hawaii, and Volcanoes National Park is nearby. (Well, actually, it's a couple hours drive away, the big island is....big).
In terms of size itself, Hilo has an airport bigger than what it needs...Hilo could, with a few modifications to the terminal, handle every bit as much traffic as Kahului...but airlines seem to prefer flying to the "sunny side" over in Kona. So Hilo has this big airport that's mostly served by just AQ
for interisland flights.
Kahului's airport is bordering on being smaller than it should be but the residents strongly opposed the plans to lengthen the runway, so there it sits.
Lihue is just about the right size.
