The World

At present, the database contains 277 countries (past & present) and regions. To keep thing simple I have split the world into 4 regions broadly based on the United Nations geoscene which is a system which divides the countries of the world into regional and subregional groups.

The 4 regions are:

Africa

Eastern Africa : Middle Africa : Northern Africa : Southern Africa : Western Africa

Americas

Northern America : Southern America : Central America : Caribbean

Europe

European Union : East Europe (North Asia (the Asian portion of Russia)) is included in this subregion : Northern Europe : Southern Europe : Western Europe

Rest of World

Central Asia : Eastern Asia : Southern Asia : South-Eastern Asia

Western Asia : Oceania : Melanesia : Micronesia : Polynesia

Unknown / Unspecified

These are airlines that either the geographic region or the country is not known
