Glasgow International Airport (GLA) is located 6.9 miles west of Glasgow city centre. It is the second busiest airport in Scotland, next to Edinburgh, and the eighth busiest in the UK. In 2014, it served 7.7 million passengers. It is operated by AGS Airports, the same firm that operates Southampton and Aberdeen Airports. It is the hub of Loganair, and used by major airlines British Airways, EasyJet, Thomson, Flybe, Thomas Cook and Jet2.
The airport opened in 1966, offering flights only in the United Kingdom and Europe. In 1975, the British Airports Authority took management and when the latter was privatized, GLA launched flights worldwide. The history of Glasgow Airport can be traced back to the 1930s. Its original site was about 3 kilometers away from Abbotsnich, now the area of Dean Park in Renfrew. Formal opening of GLA was in 1966, and it took almost 6 years to build it.Major expansions began in 1973, involving runway extension to hold larger aircrafts.
Currently, Glasgow Airport now features three piers, West for International flights, Central for domestic and East for small airlines, Scottish islands and Ireland. The Central Pier was the first one to be built among the tree, being part of the original construction in 1966. It is used by Flybe and houses the BA Executive Lounge. The East Pier was constructed late 1970s while the West Pier was part of the extension project in 1989.
