Istanbul Airport Terminal
Quick answer: Istanbul Airport (IST) has a single passenger terminal, one of the largest in the world under a single roof at about 1.4 million m². It is not split into "Terminal 1 and 2": instead, five concourses (piers) branch from one central hub. Concourses A, B, D and F handle international flights and Concourse G handles domestic (there is no separate C or E pier). Departures are upstairs and arrivals downstairs. The building is huge, so allow up to 20 to 30 minutes to reach the farthest gate on foot.
Because everything sits under one roof, IST can feel overwhelming on a first visit. This guide explains how the terminal is structured, which concourse your flight uses, how the departure and arrival levels work, how long it really takes to cross, and where the main facilities are. Opened in 2018 and in full operation since 2019, it serves around 90 million passengers a year today across five runways, with a master plan reaching 200 million.

How many terminals does Istanbul Airport have?
Just one. IST is a single terminal building that handles both international and domestic flights, and it is one of the largest passenger terminals in the world under a single roof. This trips up a lot of travellers, because the airport is so big that people assume it must be split into "Terminal 1" and "Terminal 2", or into separate A, B and C terminals. It is not. What you will see signposted as A, B, D, F and G are concourses (piers) inside the one terminal, not separate buildings. So you never need to change terminals at IST, even when connecting between domestic and international flights.
What are the concourses at Istanbul Airport?
Five concourses branch out from a central hub that holds the main duty-free and dining area. Note that the lettering skips C and E, because those sections are part of the central terminal core rather than standalone piers. Here is how they split:
| Concourse | Flights |
|---|---|
| A, B, D, F | International |
| G | Domestic only |
Your boarding pass shows the gate, and the gate letter tells you the concourse. Whichever pier you need, you reach it from the same central airside area, passing the duty-free shops and lounges on the way. There are 143 boarding bridges in total across the concourses.
How is the terminal laid out, level by level?
The flow is the usual upstairs-downstairs split. Departures are on the upper level: you arrive at the check-in islands, drop bags, clear security and passport control, then enter the central airside hub and walk out to your concourse. Arrivals are on the lower level: after landing you go through passport control and pick up bags at reclaim, then exit into the landside arrivals hall. Public transport (metro, buses, taxis) connects from the lower/ground level just outside arrivals. Transfer passengers have dedicated transfer security points and do not need to leave the secure area.
How big is Istanbul Airport, and how long does it take to walk across?
It is genuinely large. At roughly 1.4 million m² in one building, the walk from security to the farthest gate can take 20 to 30 minutes on foot. Moving walkways run along the main corridors to speed this up, but there is no internal train or shuttle bus between concourses, so all movement is on foot through the connected building. The practical takeaway: once you are airside, check how far your gate is on the screens and give yourself time, especially if you stop to shop or eat in the central hub.
What about connecting flights and minimum connection time?
The airport itself does not publish an official minimum connection time. Turkish Airlines, which runs its hub here, uses a minimum of roughly 60 to 75 minutes for international-to-international connections. If you are switching between domestic and international, or between different airlines, allow at least two hours, because you may pass through additional passport or security checks. Since everything is under one roof, connections are walk-only, so factor in the building's size.
How do you get to and from the terminal?
Several options connect at the terminal, all reached from the lower/ground level around arrivals:
- M11 metro to Gayrettepe in about 30 minutes, then change to the M2 for the city centre.
- HAVAİST buses from the ground-floor bus terminal outside arrivals, running 24/7 to Taksim, Sultanahmet and other districts.
- Taxis from the arrivals exits.
- Car parks directly next to the terminal (see our Istanbul Airport parking guide).

What facilities are in the terminal?
Most amenities sit in the central airside hub where the concourses meet. You will find the main duty-free area, a wide range of dining, and the airport lounges including the large IGA Lounge. For sleep, there are two airport hotels: YOTELAIR airside in the transit area (hourly cabins and overnight rooms) and YOTEL landside on the departures floor before security. The terminal also has multiple prayer rooms and masjids, several children's play areas, pharmacies and medical facilities spread through the building.
First-time tips for the Istanbul Airport terminal
- Use the central hub as your reference point: every concourse radiates from the same duty-free and dining core, so when in doubt, head back to the centre and follow your concourse letter.
- Check your gate's walking distance on the screens and set off early, since the farthest gates are a 20 to 30 minute walk and there is no train to shortcut it.
- Flying domestic? Head straight for Concourse G; everything else (A, B, D, F) is international.
- Connecting? Stay airside, follow the Transfer signs to the dedicated transfer security, and budget extra time if you switch between domestic and international flights.
- Need to rest between flights? YOTELAIR sits airside near the IGA Lounge for hourly cabins, while landside YOTEL is handy for very early or late departures before security.
