IST — Istanbul Airport
One enormous terminal, and a different airport across the city with a similar name
Istanbul Airport opened in 2019 as a replacement for the old Atatürk airport and is built around a single terminal building among the largest in the world under one roof. That has a real consequence for passengers: there is no shuttle between terminals because there is only one, but the walk from one end to the other can take half an hour.
The more expensive mistake here is confusing it with Sabiha Gökçen, Istanbul's other airport, which is on the Asian side of the city. They are roughly two hours apart, and an itinerary that assumes they are interchangeable does not work.
Terminals and how they connect
A single terminal
All flights, international and domestic, use one building with piers extending from a central core. Everything is inside security once you are through, which makes connections conceptually simple.
The distances are the catch
Gate-to-gate transfers of twenty to thirty minutes on foot are normal, and further at the extremities of the piers. Moving walkways help; the scale is still substantial.
Sabiha Gökçen is not this airport
SAW sits on the Asian side and mainly serves lower-cost and domestic traffic. Transferring between the two means crossing the city, which takes around two hours by road and considerably more in bad traffic.
Getting into Istanbul
Times below are realistic ranges rather than best cases. Rail journeys keep to a timetable; road journeys do not, and treating the two the same is how people miss flights.
M11 metro
35 to 45 minutes to Gayrettepe
A metro line connecting the airport with Gayrettepe on the European side, where it links into the wider network. The cheapest and most traffic-proof route in.
Havaist buses
60 to 100 minutes
Scheduled coaches to Taksim, Sultanahmet and other districts, with luggage holds. Straightforward and reasonably priced, and entirely dependent on Istanbul's traffic, which is severe.
Taxi
45 minutes to well over 90
Metered, and the distance from the new airport to the historic centre is substantial, so the fare is higher than people expect. Use official ranks and insist on the meter.
Hotel and private transfers
45 to 90 minutes
Widely offered and often the least stressful option after a long flight, with a price agreed in advance. Many hotels arrange them on request.
Connecting through IST
Everything being under one roof removes the terminal-change problem entirely, and Istanbul functions well as a transfer hub between Europe, Asia and Africa. What it does not remove is walking time — allow for twenty to thirty minutes gate to gate, and more if your arrival and departure gates are at opposite extremities. Passport control applies if your connection moves you between international and domestic flights, and those queues can be long at peak times, so ninety minutes is a floor rather than a comfortable margin for that combination.
Worth knowing before you fly
Check which Istanbul airport your ticket says
IST and SAW are two hours apart on opposite sides of the Bosphorus. Booking a connection that lands at one and departs from the other requires most of a day and a plan for crossing the city, and is very easy to do accidentally when comparing fares.
Give yourself walking time
Do not treat a ninety-minute connection here as generous. Look at your arrival and departure gates on landing and start moving; a half-hour walk plus a passport queue consumes it quickly.
Traffic makes the metro the safer bet
Istanbul's road congestion is among the worst of any major city and can double a journey without warning. If you have a flight to catch, the M11 metro is worth choosing over a car even if the door-to-door time looks similar on paper.
Terminal assignments, transit timetables and fares all change. Confirm the details that matter to your trip with the airport or transport operator before you travel.

FAQ
IST — common questions
Terminals, transfers and getting into the city.
How do you get from Istanbul Airport into the city?
The M11 metro reaches Gayrettepe on the European side in 35 to 45 minutes and connects into the wider network, which makes it the cheapest option and the one unaffected by traffic. Havaist coaches run to Taksim, Sultanahmet and other districts in 60 to 100 minutes with luggage holds. Taxis take 45 minutes to well over 90 and cost more than most visitors expect, because the airport is a long way out.
What is the difference between IST and Sabiha Gökçen?
They are two separate airports on opposite sides of Istanbul. IST is the large new airport on the European side handling most international traffic; Sabiha Gökçen, coded SAW, is on the Asian side and serves mainly domestic and lower-cost flights. Crossing between them takes around two hours by road and often longer in traffic, so an itinerary that arrives at one and departs the other needs most of a day rather than a normal connection buffer.
How long do I need for a connection at Istanbul Airport?
Because there is only one terminal, you avoid any shuttle or re-check, but the building is vast and a gate-to-gate walk of twenty to thirty minutes is normal. For an international-to-international connection, ninety minutes is a reasonable minimum and two hours is comfortable. If your connection crosses between international and domestic, add passport control, which can be slow at peak times.
