Baku Heydar Aliyev International Airport is one of the six international airports serving Azerbaijan. The airport is located 20 kilometers northeast of Baku, connected to the city by a modern highway. The airport serves as the home base for national carrier Azerbaijan Airlines and Buta Airways.  

I've been flying from this airport back to Tbilisi with Buta Airways in early August 2019, see: About Buta Airways Baku - Tbilisi fight

Two passenger terminals and two cargo terminals operate at Heydar Aliyev International Airport.

There is Vanderlande baggage-handling system in Terminal 1, as well as L-3 equipment for thorough baggage inspection and scanners designed to obtain a layered image of the internal structure of the object.

Terminal 1 operates jet bridges capable of receiving 12 aircraft simultaneously. Two jet bridges are intended for accommodating the world's largest passenger aircraft, the Airbus A380.

Terminal 1 total area is 65,000 square meters. The terminal is designed for 6 million passengers per year. It currently serves up to 3 million passengers annually. The total parking area is 20 000 m2 for 600 vehicles

Terminal 2 (much smaller) currently serves both domestic flights (South entrance) and international flights of low-cost airlines (North entrance).
