Landing essentials
Whether you can land, whether you can refuel, and how customs works here.
Overview
St Augustine Airport, KSGJ, is a towered Part 139-class field on Florida's northeast coast, roughly 28 nautical miles from the metro core it serves. Business aviation makes up the large majority of its FAA-tracked traffic, with 13,272 bizav operations recorded in 2025 against 19,857 total operations. Two paved runways plus water landing areas give the field an unusual mix of capability, though the primary hard-surface runway, 13/31, carries the bulk of jet and turboprop movements. CBP inspection services are available onsite, backed by a USDA compliance agreement, making KSGJ a workable customs stop for arriving international traffic.
Runways
Saint Augustine Airport has six runways. The longest, 17W/35W, is 12,000 ft long and 1,000 ft wide, with a water surface.

Frequently asked questions
What is the longest paved runway at KSGJ?
The longest paved runway at St Augustine Airport is 13/31, at 8,001 feet long and 150 feet wide with an asphalt surface. This is the runway most business aircraft use, since the airport's other paved strips, 06/24 and 02/20, are considerably shorter at 2,701 feet and 2,609 feet respectively. St Augustine also lists several water landing areas, including 17W/35W and 18W/36W at 12,000 feet each, but these serve seaplane operations rather than conventional traffic. For most turboprop and jet operators, runway 13/31 is the operationally relevant surface at KSGJ.
Are there restrictions on runway use for scheduled passenger flights at St Augustine?
Yes, several runways at St Augustine Airport carry restrictions for Part 121 and Part 380 operations. Runways 02/20, 06/24, 12W/30W, 17W/35W, and 18W/36W are all unavailable for scheduled passenger-carrying operations with more than 9 passenger seats and for non-scheduled passenger-carrying operations with more than 30 passenger seats. This leaves runway 13/31 as the runway available for larger-capacity passenger operations at KSGJ. Dispatchers planning scheduled or larger charter passenger flights into St Augustine should plan around runway 13/31 accordingly.
Is fuel available at KSGJ around the clock?
Self-service fuel is available 24 hours a day at St Augustine Airport with credit card payment. Jet A single-point refueling is also available at the field, supporting turbine aircraft operations. Both 100LL and Jet A fuel types are stocked at KSGJ. The airport's attendance schedule runs 0600 to 2200 local daily, but the self-service fuel option extends access beyond staffed hours for arriving or departing aircraft.
What obstacle and approach considerations apply to runway 13 at St Augustine?
Runway 13 at St Augustine Airport, KSGJ, has a road obstacle 15 feet tall located 200 feet before the runway's arrival end and 150 feet right of centerline. The approach slope to the marked displaced threshold on runway 13 is 34:1. These factors are relevant for approach planning and obstacle clearance calculations on this runway. Operators flying visual or non-precision approaches to runway 13 should account for both the close-in obstacle and the displaced threshold geometry.
What customs and agricultural clearance options does KSGJ offer international arrivals?
St Augustine Airport provides CBP inspection services onsite, along with a USDA compliance agreement covering agricultural clearance. This combination allows international arrivals to clear customs directly at KSGJ rather than diverting to another port of entry. The airport's control tower and published CTAF frequencies support inbound traffic coordination, and pilots requiring clearance delivery who cannot reach the field on FSS frequency are directed to contact Jacksonville Approach. Together these features make St Augustine a functional customs stop for business aviation crossing into the United States on Florida's northeast coast.
