Airport Overview & History
Boeing Field / King County International (KBFI) opened in 1928 and is owned and operated by King County. Long tied to Boeing's manufacturing presence, it sits about 5 miles south of downtown Seattle and today functions as one of the busiest general-aviation reliever airports in the country, handling a mix of business jets, cargo (including a UPS presence), flight training, and Boeing delivery and test flights.
Runway Capability
The field's primary runway, 14R/32L, is 10,007 feet of asphalt - long enough for heavy-iron business jets and full-size airliners. The parallel 14L/32R adds 3,709 feet for lighter traffic. With ILS, RNAV, and visual approaches and a 24-hour tower, KBFI supports reliable all-weather access for the Pacific Northwest's corporate fleet.
Charter Considerations
Because KBFI is a U.S. international airport of entry with on-field U.S. Customs, it is a practical departure and clearance point for cross-border and international charter into the Seattle area. Its close-in location - roughly a 15-to-20-minute drive from downtown - typically beats SEA for door-to-aircraft time, while three competing FBOs (Signature, Modern Aviation, and Skyservice Seattle) give charter clients fuel-price and handling options.
Safety & Planning
KBFI is a high-density, towered environment with heavy mixed traffic and immediate proximity to Seattle-Tacoma International (SEA) Class B airspace. Crews should brief on parallel-runway operations, expect sequencing with cargo and training aircraft, and coordinate clearances carefully. There is no published aircraft weight limit or noise curfew.
Seasonal & Operational Factors
The 21-foot field elevation keeps density-altitude effects minimal year-round. The dominant operational consideration is Puget Sound marine weather: low ceilings, fog, and reduced visibility are common in fall and winter, making the ILS valuable. Summer offers the best VFR conditions. De-icing planning is prudent from late autumn into early spring.
Regional Context
Seattle's technology-driven economy generates strong corporate-aviation demand, and KBFI is the metro's premier close-in business-jet field. For travelers it offers a faster, less congested alternative to commercial SEA, while still providing customs, long-runway capability, and multiple full-service FBOs within minutes of downtown Seattle, Bellevue, and the Eastside tech corridor.
