Edinburgh Airport (IATA: EDI, ICAO: EGPH) is an airport located in the Ingliston area of Edinburgh, Scotland. It was the busiest airport in Scotland in 2019, handling over 14.7 million passengers. It was also the sixth-busiest airport in the United Kingdom by total passengers in 2019. It is located 5 NM (9.3 km; 5.8 mi) west of the city centre, just off the M8 and M9 motorways. It is owned and operated by Global Infrastructure Partners, who are also a minority shareholder of Gatwick Airport. The airport has one runway and one passenger terminal and employs about 2,500 people.

In 2013, a further extension to the passenger terminal was announced, taking the terminal building up to the Edinburgh Airport tram stop. The opening of the Edinburgh Trams in May 2014 created the first rail connection to Edinburgh Airport. Whilst the number of passengers has increased, the number of flights actually decreased in 2014 due to planes operating at a higher capacity. Passenger traffic at Edinburgh Airport reached a record level in 2015 with over 11.1 million passengers and over 109,000 aircraft movements. The terminal building is currently being expanded with an investment of £40m. A new £25m expansion project involving the construction of a new 6,000m² building, housing a security hall and retail areas, is also currently underway at the airport. On 23 February 2016, Ryanair announced a growth of 20% in passenger numbers, bringing the airline’s annual passenger capacity at Edinburgh Airport to 2.5 million. This was coupled with the news of six new services to Ryanair’s winter schedule from Edinburgh, in addition to more services on its popular European destinations. In February 2016, consultancy firm Biggar Economics announced that Edinburgh Airport contributes almost £1 billion to the Scottish economy every year. As part of the expansion works, Runway 12/30 was officially withdrawn from use on 29 March 2018.
