Split Airport (; ), also known as Resnik Airport (), is the international airport serving the city of Split, Croatia. It is located from Split, on the west side of Kaštela Bay, in the town of Kaštela, and extending into the adjacent town of Trogir. In 2019, the airport was the second busiest in Croatia after Zagreb Airport handling 3.3 million passengers. The airport was the busiest in Croatia in 2021 handling 1.57 million passengers, surpassing Zagreb Airport for the first time. It is a major destination for leisure flights during the European summer holiday season and an important seasonal base for Croatia Airlines that offers flights to European cities such as Athens, Frankfurt, London and Paris. History The first grass airfield was located in Sinj and the first commercial route was opened in 1931 by the Yugoslav airline Aeroput. It linked Zagreb with Belgrade through Rijeka, Split and Sarajevo, and maintained this route until the start of the Second World War. These flights connected Split either by its Divulje seaplane station, or by the Sinj airfield. In the sixties, the airport was relocated from Sinj to Resnik. The new airport complex, designed by architect Darko Stipevski (Tehnika, Zagreb), was opened on 25 November 1966. The apron had dimensions of only 200 x 112 m and 6 parking positions with a planned capacity of 150,000 passengers. In 1968, passenger numbers already stood at 150,737 and in 1969 at 235,000. In 1967, the apron was extended for the first time to accommodate 10 aircraft. A new larger terminal building designed by architect Branko Gruica (Projektant, Mostar) was constructed and opened in 1979 to accommodate traffic for the 8th Mediterranean Games held in Split in September of that year. The largest pre-war passenger numbers were achieved in 1987 totalling 1,151,580 passengers and 7,873 landings. In 1991, the passenger figures dropped to nearly zero, as the war in the former Yugoslavia broke out. In the years that followed, most of the traffic were NATO and UN cargo planes, such as the C-5 Galaxy, MD-11, Boeing 747 and C-130 Hercules. After 1995, the civilian traffic figures began rising again, and eventually surpassed the 1987 record in 2008. In 2005, the terminal got a major facelift by architect Ivan Vulić (VV-Projekt, Split) adding one more gate, the glass façade, as well as the award-winning Airport entrance structure consisting of steel/fabric "trees" illuminated by multi-colour LEDs.
