Salalah International Airport (IATA: SLL, ICAO: OOSA) stands as the Sultanate of Oman’s second major international gateway after Muscat International Airport. Situated on the picturesque Salalah coastal plain in the Dhofar Governorate, just 5.5 kilometers (3.4 miles) northeast of the city center, the airport facilitates regional travel and select intercontinental charter flights from Europe. Engage was entrusted with the critical task of replacing the airport’s aging power cradle system.
