Ben Gurion International Airport, commonly known by the Hebrew-language acronym Natbag, is the main international airport of Israel. Situated on the northern outskirts of the city of Lod, it is the busiest airport in the country. It is located 45 kilometres (28 mi) to the northwest of Jerusalem and 20 kilometres (12 mi) to the southeast of Tel Aviv. It was known as Lod Airport until 1973, when it was renamed in honour of David Ben-Gurion (1886–1973), the first prime minister of Israel. The airport serves as a hub for El Al, Israir Airlines, Arkia, and Sun d'Or, and is managed by the Israel Airports Authority.
