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]}

Addis Ababa (sometimes spelled Addis Abeba, the spelling used by the official Ethiopian Mapping Authority) is the capital city of Ethiopia. (In Ethiopian languages: Amharic, Addis Abäba [ad�?i�?s aβəβa] "new flower"; Oromo, Finfinne;Ge'ez ኣዲ�?� ኣበባ) It is the largest city in Ethiopia, with a population of 3,384,569 according to the 2007 population census.

As a chartered city (ras gez astedader), Addis Ababa has the status of both a city and a state. It is where the African Union and its predecessor the OAU are based. It also hosts the headquarters of the United Nations Economic Commission for Africa (UNECA) and numerous other continental and international organizations. Addis Ababa is therefore often referred to as "the political capital of Africa", due to its historical, diplomatic and political significance for the continent. The city is populated by people from different regions of Ethiopia – the country has as many as 80 nationalities speaking 80 languages and belonging to a wide variety of religious communities. It is home to Addis Ababa University. The Federation of African Societies of Chemistry (FASC) and Horn of Africa Press Institute (HAPI) are also headquartered in Addis Ababa.
