Helsinki-Vantaa Airport, or simply Helsinki Airport, is the main international airport serving Helsinki, the capital of Finland, as well as its surrounding metropolitan area, and the Uusimaa region in Finland. The airport is located in the neighbouring city of Vantaa, about 5 kilometres (3 mi) west of Tikkurila, the administrative centre of Vantaa and 9.2 NM north of Helsinki's city centre. The airport is operated by state-owned Finavia. The facility covers a total of 1,800 hectares of land and contains three runways.

An international airport is an airport with customs and border control facilities enabling passengers to travel between countries around the world. International airports are usually larger than domestic airports, and feature longer runways and have facilities to accommodate heavier aircraft such as the Boeing 747 and the Airbus A380 commonly used for international and intercontinental travel. International airports often host domestic flights, which helps feed both passengers and cargo into international ones.
