Glasgow Airport — Glasgow, United Kingdom

GLA occupies a site in Paisley, Renfrewshire, several miles west of Glasgow's city center, and has served as Scotland's principal gateway for transatlantic and long-haul European traffic since replacing the older Renfrew Aerodrome in the mid-1960s. As the country's second-busiest airport behind Edinburgh, it handles a mix of scheduled carriers, low-cost operators, and seasonal holiday charters, reflecting Glasgow's dual identity as an industrial powerhouse turned cultural and commercial hub. The airport should not be confused with Glasgow Prestwick, a separate facility further south along the Ayrshire coast historically used for cargo and budget flights. Ground transport links connect the terminal to the city center by dedicated bus services, though unlike Edinburgh's tram-linked airport, Glasgow has debated rail connections for years without completion. Periodic expansion has modernized the terminal to keep pace with passenger growth.
