Split Airport, also known as Resnik Airport or Zračna luka Split in Croatian, is the international airport serving the city of Split, Croatia. It is located 19 km from Split, on the west side of Kaštela Bay, in the town of Kaštela, and extending into the adjacent town of Trogir.

The airport has 2 terminals and a capacity of handling up to 5 million passengers per year. The capacity was increased in 2019 where an expansion increased the terminal areas from 14,000 m2 to 50,000 m2.

Split Airport connects Croatia with over 20 countries and 65 destinations, and is operated by 40 airlines flying to and from Split. Most of the destinations are seasonal (during the summer), with 9 destinations operated year-long, mostly by the national carrier, Croatia airlines and its affiliates.

Due to significant increase in passengers’ numbers, especially during the summer months, an expansion project was completed in summer of 2019, adding more than three times the floor space of the original terminal building and increasing the capacity to 5 million passengers per year. The original terminal has been refurbished and is still being used for some international departures, while check in, all domestic departures as well as both international and domestic arrivals including baggage claim is located in the new areas.

As a part of the expansion project an enclosed bridge was built over the state road D409 taking passengers to the newly built parking lot, bus terminal as well as rental car facilities.
