The Tripoli International Airport (IATA: TIP, ICAO: HLLT) (Arabic: مطار طرابلس العالمي) is an international airport that serves Tripoli, Libya. It is operated by the Civil Aviation and Meteorology Bureau of Libya and is the nation's largest airport.^{[citation needed]} Located in the town of Ben Ghashir 34 kilometres (21 miles) south of the city centre, the airport is a hub for Libyan Airlines; it is also a hub for Afriqiyah Airways and Buraq Air.

With the closure of the National Terminal as part of the construction of the new airport, all flights, international and domestic, leave the airport from the main International Passenger Terminal. The terminal capacity is 3 million passengers a year. The airport handled 2.1 million passengers in 2007, and over 3 million passengers in 2008. Two new terminals were to be built within the next several years which would bring the total capacity of the airport to 20 million – the first new terminal was due to open by March 2011.^{[dated info]}

Libyan Airlines operates the most weekly departures from the airport. Transport to and from Tripoli city center usually involves taking a taxi or shared taxi. Tour operators offer coaches to and from the airport connecting it with numerous hotels in the city centre.

Tripoli is the capital and largest city in Libya. It is also known as Tripoli-of-the-West (Arabic: طرابلس الغرب‎ Ṭarābulus al-Gharb), to distinguish it from Tripoli, Lebanon. It is affectionately called The Mermaid of the Mediterranean (Arabic: عروسة البحر‎ ʼarūsat el-baḥr; lit: "bride of the sea"), describing its turquoise waters and its whitewashed buildings. Tripoli (English pronunciation: /ˈtrɪpɵli/) is a Greek name that means "Three Cities", introduced in Western European languages through the Italian Tripoli. In Arabic: طرابلس‎ it is called Ṭarābulus ( pronunciation (help·info), Libyan Arabic: Ṭrābləs  pronunciation (help·info), Berber: Ṭrables, from Ancient Greek: Τρίπολις Trípolis). As of 2011, the Tripoli metropolitan area (district area) had a population of 2.2 million. The city is located in the northwest part of the country on the edge of the desert, on a point of rocky land projecting into the Mediterranean and forming a bay.

The city includes the Port of Tripoli and the country's largest commercial and manufacturing centre. It is also the site of the University of Tripoli. The vast Bab al-Azizia barracks, which includes the former family compound of Muammar Gaddafi, is also located in the city; Gaddafi largely ruled the country from his residence in this barracks.

An international airport is an airport that can accommodate international flights. They are typically equipped with customs and immigration facilities. Such airports are usually larger, and often feature longer runways and facilities to accommodate the large aircraft commonly used for international or intercontinental travel. International airports often also host domestic flights (flights which occur within the country), to serve travellers to and from these regions of the country.

In many smaller countries most airports are international airports, so the concept of an "international airport" has little meaning. In certain countries however, there is a sub-category of limited international airports which handle international flights, but are limited to short-haul destinations (often due to geographical factors) or are mixed civilian/military airports.^{[citation needed]}

Many airports with regularly scheduled international service have the word "International" in their official names, but others, including such major airports as London Heathrow Airport, Paris-Charles de Gaulle Airport, Frankfurt Airport, Detroit Metropolitan Wayne County Airport and George Bush Intercontinental Airport do not. Conversely, some airports which call themselves international airports, especially in smaller United States cities, in fact have no scheduled international airline passenger service but do have customs and immigration facilities serving charter, cargo and general aviation flights. At many of these airports customs and immigration services are only available with several hours advance notice. One example of such an airport is Gerald R. Ford International Airport in Grand Rapids, Michigan. A few, such as Gary/Chicago International Airport in Gary, Indiana, are in fact not international airports at all; they are not designated as airports of entry but aspire to become such in the future and added "international airport" to their names as a marketing tool.^{[citation needed]}
