The new apron designed by Ivan Vulić, Ivan Radeljak and Mate Žaja was constructed in 2011 with a capacity slightly over the old one but with better security conditions. The cost of this investment was €13 million leading to 34,000 m2 of new parking space for aircraft as well as space for future administrative works below the apron. The lower level houses warehouses, workshops, offices and other objects that will support the new 34,500 m2, HRK 455 million terminal building that is being built next to it. New apron features an unusual sound barrier on the south side which can be closed when an aircraft is close by and opened in all other times to allow for fairly unobstructed view of the Adriatic sea from the terminal building. The airport's busiest time are the months of June, July and August due to a large influx of tourists for the European summer holiday period. Weekends are the busiest part of the week with more than 200 flights and some 50,000 passengers. On the grounds of the airport there are some 1000 olive trees. Expansion (2019) 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. 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 and rental car facilities. The decision not to include any jet bridges in the new expansion has been justified because of limited apron space as well as the fact that majority of the airlines at the airport are low-cost carriers.
