Whidbey Island Naval Air Station (Ault Field) is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 8,001-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 8,001 ft (2,439 m), a heavy-class field. Representative aircraft that operate comfortably here include the Gulfstream G550, Falcon 7X, and Bombardier Global 5500. In practice this most heavy and super-midsize jets operate here without restriction.

Whidbey Island Naval Air Station (Ault Field) sits near sea level at 47 ft.

Local operations run on America/Los_Angeles. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.

SkyAccess inventory for KNUW updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Regional fields like KNUW are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.
