Istanbul Airport IST Guide: Transfers, Lounges, Metro and Tips
Istanbul Airport, Istanbul, Türkiye: terminals, getting to the city, security, lounges and connections.
Quick answer: Istanbul Airport (IST) is Turkish Airlines' hub and handles its flights from the US. Everything happens in one large terminal: international gates are on piers A to F and domestic flights use a separate area. Passengers connecting between two international flights without collecting bags stay airside and pass a transfer security check. The M11 metro runs from the airport to Gayrettepe for the M2 line toward Taksim, and Havaist buses run 11 routes into the city. Do not confuse IST with Sabiha Gökçen (SAW), Istanbul's other airport on the Asian side.
Facts checked November 2026. Schedules and entry rules change, so confirm with the airline and the official government site before you travel.

How Istanbul Airport is laid out
Istanbul Airport has one very large terminal building. International departures and domestic departures are in separate areas with their own entrances, so follow the signs for your flight type from the curb. International boarding gates are on piers A to F, and domestic flights use a separate area.
Walking distances are long. The airport runs the iGA Buggy, a paid electric cart service between the piers; check the airport's site for stops and who rides free.
Turkish Airlines, which flies to Istanbul from many US cities as of recent schedules, uses IST as its hub, so most passengers from the US arriving here are either visiting Istanbul or connecting onward on Turkish Airlines. Check with the airline for the current US schedule.
International transfers at IST
If you are connecting from one international flight to another and your bags are checked through to your final airport, you do not pass passport control. Follow the transfer signs to the transfer security checkpoint, then go up to the departures floor and find your gate on the screens.
If your bags are not checked through, or you want to leave the airport, you pass passport control into Türkiye, collect your bags and check in again. That requires the right entry documents for your passport, so check the official Republic of Türkiye e-Visa website before you travel.
If a connection is missed or cancelled, go to your airline's transfer desk inside the terminal. Turkish Airlines handles rebooking for its own passengers at its transfer desks. Give yourself extra time, because the walk between the arrival pier and the departure pier can be long.
Long layovers: Touristanbul, YOTEL and rest areas
Turkish Airlines runs Touristanbul, a free guided city tour for passengers on international-to-international connections with a layover of 6 to 24 hours. The ticket number must start with 235 and both flights must be on the same booking. The tour includes transport, an English-speaking guide, a meal that varies with the schedule, and museum entrance fees. Register at the Touristanbul desk, in the arrivals hall or in the transfer area, at least 30 minutes before the tour starts.
For long connections Turkish Airlines also offers a hotel program for eligible passengers; the minimum layover depends on the fare and cabin, and the voucher must be issued before the journey starts, so ask when you book.
Inside the terminal, YOTEL has rooms on both sides of passport control. YOTELAIR, the airside part, is in the duty-free area and can be booked only by passengers on international flights. The airport also has free nap zones and paid sleeping cabins in the international departures area.
Lounges at Istanbul Airport
Turkish Airlines runs a Business Lounge for business class passengers and Star Alliance business passengers, and a Miles&Smiles Lounge for Star Alliance Gold members and Miles&Smiles elite members. Both are in the international departures area.
The iGA Lounge is the airport's own lounge on the international departures floor. You can enter with a purchased lounge pass, iGA Pass membership, or through an eligible airline or partner program. There is also a SkyTeam lounge in the international area for passengers of SkyTeam airlines.
Entry rules depend on your ticket, status and membership, so check the lounge's own page before you travel.
Getting into Istanbul: M11 metro, Havaist and taxis
The M11 metro runs from Istanbul Airport through Kağıthane to Gayrettepe, where you change to the M2 line for Levent, Şişli and Taksim. The line was extended past the airport to Halkalı in June 2026. Pay with an Istanbulkart. The trip to Gayrettepe takes well over half an hour, and journeys to the old city around Sultanahmet need further changes.
Havaist buses run many routes between the airport and the city, including lines to Taksim through Beşiktaş. You board on the transportation floor, level -2. Accessible midibuses are available for wheelchair users if you ask at a Havaist counter at least an hour ahead.
Taxis wait outside arrivals and are the simplest choice late at night or with heavy bags. The airport is far from the centre, so allow plenty of time for traffic, especially in the evening rush.
Practical tips for Istanbul Airport
Check which Istanbul airport your ticket uses. Sabiha Gökçen (SAW) is a separate airport on the Asian side of the city, far from IST, and a self-booked connection between the two is a common and expensive mistake.
Airlines generally advise arriving 3 hours before an international flight. The terminal is very large, so add time to reach your gate, or book the iGA Buggy if walking far is hard for you.
Duty-free shopping is spread through the international departures area. Check the gate on the screens as soon as you pass security, because the far ends of the piers are a long walk.
