Antoine-Simon International Airport (IATA: CYA, ICAO: MTCA) is the primary commercial airport serving Les Cayes, the largest city in southern Haiti. It is named after Antoine Simon, a former president of Haiti who was born in the region. The airport provides essential air connectivity for a part of the country that is otherwise difficult to reach overland. The airport handles limited scheduled domestic and regional services, connecting Les Cayes to Port-au-Prince and occasionally to other Caribbean destinations. Its infrastructure reflects the modest scale of air traffic in this part of Haiti, though it carries international designation. The facility has faced operational challenges over the years, including damage from natural disasters such as the 2010 earthquake and the 2021 earthquake that severely impacted the southern peninsula. Reconstruction and improvement efforts have been ongoing to restore and upgrade capacity.
