Lleida-Alguaire Airport — Lleida, Spain

ILD is Lleida-Alguaire Airport, serving the city of Lleida in Catalonia, Spain, roughly midway between Barcelona and Zaragoza. Opened relatively recently compared to Spain's older regional airports, ILD was built to serve the Lleida province, including nearby ski resorts in the Pyrenees such as those in the Aran Valley, and to support the region's agricultural export economy. The airport has faced fluctuating passenger volumes over the years, with airline route offerings changing based on demand for both leisure travel to the mountains and connections tied to regional business. ILD's relatively modern terminal and single runway reflect its design as a smaller complement to Catalonia's larger Barcelona hub.
