Frequently asked questions
What is the longest runway at KSWO?
Stillwater Regional's primary runway, 17/35, is a concrete surface measuring 7,401 feet long and 100 feet wide. This is the longest paved surface at KSWO and the one used for most business aviation arrivals given its length margin. A secondary asphalt runway, 04/22, spans 5,002 feet by 75 feet and provides a crosswind option. Both runways are paved, giving operators flexibility depending on wind conditions. Lighting includes MALSR on runway 17 and REIL on runway 35 to support approaches.
Is there a fuel availability window at Stillwater Regional Airport?
Stillwater Regional Airport lists an attendance schedule of 0800-2200 every day, and both 100LL and Jet A fuel are available on the field. Fuel access outside those posted hours requires prior permission, according to the airport's operational remarks. Operators planning arrivals or departures outside the daily attendance window should arrange after-hours fuel in advance rather than assume walk-up service. General aviation transient parking on the Hangar 1 ramp also requires contacting the FBO on UNICOM or by phone. Ramps at KSWO are uncontrolled, so coordination is on the pilot.
Does KSWO have customs clearance on site?
Stillwater Regional Airport, identified by the code KSWO, does not have onsite customs service. The nearest customs facility is at KOKC, located approximately 52.51 nautical miles away. Operators arriving from international origins need to plan a stop at that facility or coordinate clearance procedures in advance, since KSWO itself cannot process customs. This distance should be factored into fuel and routing planning for any flight requiring inbound customs clearance. There is no indication in the airport's data of any customs arrangement available directly at the field.
Are there weight or pavement strength restrictions for operations at Stillwater Regional?
Stillwater Regional lists two pavement classification values for its runways, PCR 158/R / C/W / T and PCR 582/R / C/W / T, reflecting the differing pavement strength of the two runway surfaces. Operations above the applicable PCR value require prior permission, per the airport's general remarks. This means heavier aircraft exceeding the rated pavement strength cannot simply arrive unannounced. Dispatchers should confirm their aircraft's pavement loading against these published PCR values before filing to KSWO. Coordination ahead of arrival avoids delays tied to the PPR requirement for over-limit operations.
When is business aviation traffic busiest at Stillwater Regional Airport?
Traffic at Stillwater Regional Airport, KSWO, is not evenly distributed across the year, with the FAA TFMSC data showing a peak in October at 691 operations. Other elevated months include April at 582 operations and September at 531 operations, while the traffic trough falls in December at 297 operations and May at 313 operations. This pattern suggests business aviation activity at KSWO is concentrated in specific parts of the year rather than flat month to month. Dispatchers scheduling around these peak periods may find ramp and parking demand higher than average. The airport recorded 5,437 annual business aviation operations against a total of 8,813 operations in 2025.
