Saint Louis Airport (IATA: XLS, ICAO: GOSS) serves the city of Saint Louis, Senegal's former colonial capital located near the mouth of the Senegal River in the country's northwest. The airport provides regional air access to one of West Africa's most historically significant cities, a UNESCO World Heritage Site known for its distinctive island architecture. The facility operates as a smaller regional airport, handling domestic and limited international traffic. It plays an important role in connecting Saint Louis to Dakar and other regional destinations, supporting tourism and commerce in the area. Air Sénégal and other regional carriers have historically operated services here, though flight frequency and airline presence have fluctuated over the years. The airport's modest infrastructure reflects the scale of demand in this secondary Senegalese city.
