Sandpoint Airport (ICAO: KSZT, FAA LID: SZT) is a county-owned public-use airport in the northwest United States, located two nautical miles (4 km) north of the central business district of Sandpoint in Bonner County, Idaho. The airport is also known as Dave Wall Field. Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned SZT by the FAA but has no designation from the IATA (which assigned SZT to San Cristóbal de las Casas National Airport in Mexico).
