Ben Gurion International Airport, commonly known by the Hebrew-language acronym Natbag, is the main international airport of Israel. Situated on outskirts north of the city of Lod and directly south of the city of Or Yehuda, 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, Arkia, and Sundor, and is managed by the Israel Airports Authority.
