Frequently asked questions
Is Jet A fuel available at KGGW?
Yes, Wokal Field / Glasgow-Valley County stocks Jet A1+ in addition to 100LL. The airport is attended daily from 0600 to 2000 local, which covers the window when fuel service is normally available. Dispatchers should plan arrivals within that attendance window rather than assuming after-hours fuel access. KGGW is untowered, so fuel and ramp coordination happens over CTAF rather than through a tower frequency. Confirm quantities and turnaround expectations directly with airport staff before finalizing a fuel stop here.
What runways does KGGW offer for planning purposes?
Glasgow-Valley County (KGGW) has two paved asphalt runways. Runway 12/30 is the longer of the pair at 5,002 feet with a 100-foot width, and runway 08/26 measures 5,000 feet with a 75-foot width. Both surfaces support the full range of business aviation traffic the airport sees. Lighting includes REIL on runways 8, 12, 26, and 30, plus MIRL on both runway pairs, all pilot-activated on CTAF. PAPI is available on all four runway ends and operates continuously.
Is there customs clearance available at KGGW?
Wokal Field / Glasgow-Valley County does not have onsite customs processing. The nearest customs facility is located at 8U3, approximately 67.51 nautical miles away. Crews requiring customs clearance near KGGW need to route through that facility instead, which adds routing considerations for international arrivals. Since KGGW itself has no customs designation in the data, flight plans involving foreign origin traffic should account for the diversion to the nearest customs airport ahead of time.
How does business aviation traffic at KGGW vary through the year?
Business aviation traffic at Glasgow-Valley County shows a concentrated pattern, with the FAA TFMSC data recording 1,430 annual business aviation operations out of 2,778 total operations in 2025. Monthly counts peak in February at 153 operations and again in October and January at 138 each. The lowest month is September at 95 operations. This shape means dispatchers scheduling around KGGW should expect somewhat heavier traffic in winter and early autumn shoulder months compared to the summer season.
What should crews know about surface conditions monitoring at KGGW?
Surface conditions at Wokal Field / Glasgow-Valley County are unmonitored between 2000 and 0600 local time. This falls outside the airport's stated attendance schedule of 0600 to 2000, so crews operating overnight or in early morning hours should not expect updated field condition reports during that window. Given the region's winter snow days, this matters most from late fall through early spring. Pilots planning operations in the unmonitored window should treat surface condition information as unconfirmed until the airport reopens for the day.
