Frequently asked questions
What runways are available at KSTL for business aviation arrivals?
St Louis Lambert International operates four paved concrete runways, giving dispatchers several options depending on wind and traffic flow. The longest is 12R/30L at 11,020 feet, followed by 12L/30R at 9,013 feet and 11/29 at 9,000 feet. A shorter fourth runway, 06/24, measures 7,603 feet. All four runways are 150 feet wide, and KSTL is a towered field, so runway assignment is coordinated through ATC based on operational conditions at the time of arrival or departure.
Does KSTL have on-site customs clearance for international arrivals?
Yes, St Louis Lambert International has customs services on site. CBP inspection services are available, and the airport also holds a USDA compliance agreement, which is relevant for flights carrying agricultural cargo or products subject to inspection. Because clearance is handled directly at KSTL rather than at a nearby field, crews do not need to route through another customs airport of entry. Dispatchers planning international legs into St Louis should still confirm inspection availability and any advance notice requirements with the appropriate authority ahead of arrival.
What fuel types are available at KSTL?
St Louis Lambert International offers both 100LL avgas and Jet A fuel, covering the needs of piston and turbine operators alike. The airport operates on an ALL / ALL / ALL attendance schedule, meaning fuel and field services are staffed year-round without seasonal gaps. With business aviation operations exceeding 15,000 annually according to FAA TFMSC data, fuel availability at KSTL is well established for a facility of this traffic tier. Crews should still confirm specific service hours and any fuel-uplift coordination with the field prior to arrival, particularly for larger turbine aircraft.
Are there taxiway restrictions at KSTL that affect larger business jets?
Yes, several taxiways at St Louis Lambert International carry wingspan-based restrictions that matter for larger business jet operators. Taxiway Victor 2 and Taxiway Kilo 1 are both unavailable to B-767 or larger aircraft with a wingspan of 118 feet or greater. Taxiway Echo, between Taxiway November and Taxiway Lima, is restricted to B-767 or smaller aircraft when aircraft are parked on the Echo pad. B-737 aircraft with a wingspan greater than 79 feet but less than 118 feet must perform judgmental oversteering rather than cockpit-over-centerline steering on Taxiway Victor 2 while taxiing.
Is business aviation traffic at KSTL evenly distributed throughout the year?
No, business aviation traffic at St Louis Lambert International shows a seasonal pattern, with activity concentrated in the spring and mid-to-late fall months. Monthly bizav operations peak around May and October, each exceeding 1,480 operations according to FAA TFMSC data, while January and February sit near 1,080 to 1,100 operations. November is the lowest month at 1,157 operations. Dispatchers planning trips into KSTL during peak spring or fall periods should account for potentially higher ramp and taxi congestion tied to this seasonal concentration.
