Herzliya Airport is a small airport located in the city of Herzliya, Israel. The airport is located about 15km north of Tel Aviv and is the closest airport to the city. The airport was opened in 1948, to serve the needs of the newly-created State of Israel. The airport was initially used for military purposes, and it was only in the 1970s that it was opened to civil aviation.

The airport was originally named Herzliya Airport, but in 1999 it was renamed Sde Dov Airport, after the nearby Sde Dov ("Field of Dov") neighborhood. The name was chosen to honor Dov Hoz, the first commander of the Israeli Air Force and the founder of the airport.

The airport code for Herzliya Airport is HRZ. The code was determined by the International Air Transport Association (IATA) in accordance with its standard codes. The code is derived from the first two letters of the airport's name, Herzliya.

Herzliya Airport currently has about 30 flights per day, with most of them operating to and from Tel Aviv. The airport is served by several airlines, including Israir, El Al, Arkia, and Sun D'Or. In addition, the airport has recently seen an increase in charter flights operated by various international airlines.

Herzliya Airport is currently undergoing an expansion project that will increase its capacity and add a new terminal. The project is expected to be completed in 2021 and will greatly improve the airport's facilities and services.

Herzliya Airport is an important gateway to Israel and serves as a vital link between the country and the rest of the world. With its expansion project, the airport is expected to become even more important in the years to come.
