Quillayute Airport covers an area of 739 acres (299 ha).

For the 12-month period ending December 31, 2022, the airport had 6,700 aircraft operations: 97% general aviation and 3% military.

In the Master Planning effort currently underway, it is the intent, in the long-term plan, to remove the displacement on runway 4/22 in the future, and reopen runway 12/30 at a shortened length.
