Southwest Washington Regional Airport

Southwest Washington Regional Airport (KKLS) is a medium airport in Kelso, WA. Pilots and dispatchers reference it by ICAO code KKLS or IATA code KLS. It sits in North America.

Southwest Washington Regional Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 4,391-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 4,391 ft (1,338 m), a light-jet-class field. Representative aircraft that operate comfortably here include the Phenom 300, Citation CJ4, and Learjet 75. In practice this limits operations to light jets, turboprops, and short-field-capable aircraft.

Southwest Washington Regional Airport sits near sea level at 20 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 KKLS 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 KKLS 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.
