Overview & History
Renton Municipal Airport (KRNT/RNT), officially renamed Clayton Scott Field in 2005, occupies the south end of Lake Washington in Renton, just southeast of Seattle. The airport is inseparable from Boeing: it sits directly adjacent to the Boeing Renton factory, where the 737 MAX 7, 8, 9, and 10 are assembled, and serves as the departure point for every newly built 737's first flight. Alongside that industrial role, it is a busy general aviation field with a large based-aircraft fleet, flight schools, and floatplane operations.
Runway Capability
The single runway 16/34 provides 5,382 feet of asphalt/concrete at 32 feet MSL. That length supports light jets and most midsize jets with normal payloads, but it is not a heavy-jet runway. Operators of super-midsize and large-cabin aircraft should run performance numbers for their specific weight and weather, and will frequently prefer Boeing Field for longer trips.
FBO & Ground Services
Vesper Aviation is the field's full-service FBO, handling Jet A and 100LL fuel, hangar and transient parking, crew cars, and rental-car coordination. Several flight-training and maintenance operators (Rainier Flight Service, Pro-Flight Aviation, AcuWings) also work the field, but Vesper is the operator charter crews and business jets coordinate with for fuel and handling. Confirm after-hours availability in advance.
Charter Considerations
For travelers headed to Renton, south Seattle, Bellevue, or the Kent Valley, KRNT can be the most convenient arrival point, putting passengers minutes from the south Lake Washington corridor. Because the field favors light and midsize aircraft, The Jet Finder matches your mission to an appropriately sized jet positioned in the Pacific Northwest, and will recommend Boeing Field when a larger cabin, longer range, or U.S. Customs is required.
Safety & Planning
Renton is towered, so expect standard ATC coordination and sequencing — traffic can include 737 test flights, floatplanes on Lake Washington, and active GA training, so situational awareness matters. A voluntary noise-abatement program asks operators to favor daylight departures and avoid repeated overflights of Renton neighborhoods; there is no federally enforced curfew, but courteous compliance is expected. There are no customs services on the field.
Seasonal & Operational Factors
The Pacific Northwest marine climate brings frequent low ceilings, rain, and morning fog from roughly October through May, making the RNAV (GPS) approaches and instrument currency valuable. Summer offers the best VFR conditions. The 32-foot field elevation means density altitude is rarely a performance concern, so winter weather and traffic sequencing — not runway-length-vs-heat — drive most planning decisions at this field.
Regional Context
KRNT is one of several Seattle-area general aviation options. Boeing Field (KBFI), roughly 8 miles north, is the region's primary business-aviation gateway with long runways, multiple FBOs, and U.S. Customs. Sea-Tac (KSEA) handles airline traffic. Renton's niche is convenient, lower-traffic access for light and midsize jets serving the south Lake Washington and Eastside markets.
