City of Derry Airport (IATA: LDY, ICAO: EGAE), previously known as RAF Eglinton and Londonderry Eglinton Airport, is a regional airport located 7 mi (11 km) northeast of Derry, Northern Ireland. It is located on the south bank of Lough Foyle, a short distance from the village of Eglinton and 8 mi (13 km) from the city centre. A military base until the 1950s, the airport, known locally as Eglinton Airport, had limited commercial services until the 1990s when it was redeveloped to service larger aircraft. The airport was also renamed as City of Derry Airport at that time. The redevelopment enabled an increase in passenger numbers from a few thousand a year, to a peak of 438,996 in 2008. The airport experienced a decline in passenger numbers in 2009–21, partially due to the COVID pandemic and underfunding, and reached a low of 73,024 in 2021. Passenger numbers then partially recovered, and in 2024, 179,095 passengers used the airport.
