Istanbul Atatürk Airport

Istanbul Atatürk Airport is the main international airport serving Istanbul, and the biggest airport in Turkey by total number of passengers, destinations served and aircraft movements. Opened in 1924 in Yeşilköy, on the European side of the city, it is located 24 km (15 mi) west of the city centre and serves as the main hub for Turkish Airlines.

The city's other, smaller, international airport is Sabiha Gökçen International Airport. As of 2017, 273 destinations are served from Istanbul-Atatürk, making it the airport with the second-most destinations worldwide after Frankfurt Airport.

I've visited Istanbul Ataturk airport several times, mostly for layover flights, with Tbilisi being the most conected flight.

Istanbul Atatürk Airport features two main passenger terminals which are interconnected to each other:

Domestic Terminal is the older and smaller of the two terminals and exclusively handles domestic flights within Turkey. Until the opening of the International Terminal, it used to be the airport's international terminal. Domestic Terminal features its own check-in and airside facilities on the upper floor that lead to twelve departure gates (101-112) which are equipped with jet bridges.On the ground level there are five baggage reclaim belts as well as a curbside independent from the International Terminal.

The International Terminal was inaugurated in 2000 and is used for all international flights. It features a large main hall containing eight check-in isles and a wide range of airside facilities such as shops and restaurants. The departures area consists of 27 gates (201-226) which are all equipped with jetbridges as well as several bus-boarding stands. The arrivals floor below is equipped with 11 baggage reclaim belts. The International Terminal is able to handle widebody aircraft such as Turkish Airlines' Boeing 777-300ERs.

There is also an additional terminal for general aviation to the northwest of the main areas as well as a dedicated cargo terminal including sections for radioactive and refrigerated freight.
