Heydar Aliyev International Airport — Baku, Azerbaijan

Perched on the shore of the Caspian Sea, GYD carries the name of Heydar Aliyev, the Soviet-era leader turned independence-period president whose family has shaped modern Azerbaijan. The terminal that opened in the mid-2010s drew international attention for its interior of cocoon-shaped wooden lounges and sweeping white curves, a design that earned Baku's airport a reputation well beyond its passenger numbers. Positioned along routes linking Europe, the Middle East, and Central and South Asia, the facility serves as the principal base for Azerbaijan Airlines and hosts Silk Way's dedicated cargo operations, reinforcing Baku's ambitions as a logistics crossroads on the old Silk Road. Oil wealth has financed much of the surrounding infrastructure boom, and the airport itself is frequently held up as a symbol of that transformation. Passengers connecting through the Caucasus increasingly find themselves routed through this rapidly modernized gateway.
