Public transport from Istanbul's airports: what goes where

Havaist is the airport bus network for IST. According to istairport.com, it runs 11 routes between the airport and the city, and the buses leave from the Transportation floor, level −2, directly below the terminal.

• There is no seat reservation: you buy a ticket and board at the stop for your line.
• Lines run to hubs across the city, and each line has its own timetable on hava.ist.
• The airport says accessible Havaist midibuses are available for wheelchair users and advises arranging them in advance.
• The Havaist call centre is on 0850 888 33 34.

City buses run by İETT leave from the same floor −2. The airport lists five İETT routes to the city and notes that these buses are wheelchair accessible.

The M11 line connects Istanbul Airport with Gayrettepe, in the business district on the European side, and in the other direction with Halkalı. The airport says the section between Halkalı and Arnavutköy opened on 20 June 2026.

The metro is the option least affected by road traffic, which makes it attractive at rush hour. The trade-off is the change of line and the walk at the far end, both of which matter more the more you carry.

• For Taksim, change at Gayrettepe to the M2 line.
• For the Old City, plan the connection on metro.istanbul before you travel, as it involves more than one change.
• With large suitcases, check the station lifts on the route you plan, because transfers between lines can involve long corridors.

Sabiha Gökçen has its own airport bus company, Havabus. Its website lists lines between the airport and Taksim, Kadıköy, Yenisahra and Sakarya. The SAW airport describes white Havabus buses parked in front of the arrivals-floor exits.

• Taksim line: crosses to the European side and ends near Taksim Square.
• Kadıköy line: stays on the Asian side and ends at the Kadıköy pier, where ferries leave for the European shore.
• Late flights: Havabus says it runs extra buses for delayed planes in the small hours on its Istanbul lines; check the timetable on havabus.com for the night you land.

The M4 metro line has served Sabiha Gökçen since 2 October 2022. It runs along the Asian side towards Kadıköy, with connections to other lines and to Marmaray, the rail tunnel under the Bosphorus.

Both SAW options leave you at a hub rather than an address. From the Kadıköy pier or a metro station you still need a taxi, a walk or another line to reach your street, so check that last stretch on a map before deciding.

Most public transport in Istanbul is paid with the Istanbulkart, a rechargeable card valid on buses, the metro, ferries and Marmaray. At SAW the airport sells it at the İETT kiosks near the bus area.

• Keep the card topped up before a long ride, as the readers at the gates do not let you through on an empty balance.
• Marmaray has no station at either airport, so you reach it only after a metro or bus ride.
• Timetables are published by each operator and can change at short notice, especially at night and on holidays.

For an independent traveller with a backpack and an address near a metro station, public transport is a sensible and cheap way in. The picture changes with children, heavy bags, a late landing or an address far from the stops.

Public transport takes you to a hub, and the last stretch to the hotel is up to you. In Istanbul that stretch can mean cobbled lanes, steps and steep streets, which are hard work with suitcases.

• Groups and families: one per-vehicle fare covers everyone, up to six people in the Eco Van or sixteen in the Sprinter.
• Night landings: the driver meets you at the arrivals exit whatever the hour, and the fare does not change.
• Cross-side hotels: a Kadıköy hotel from IST or a Sultanahmet hotel from SAW means several changes by public transport and a single ride by car.
• Return to the airport: a pick-up at the hotel door at a set time, instead of carrying luggage to a stop.

A transfer from IST to any European-side address costs €50 in the Eco Van, and from SAW to any Asian-side address also €50. Crossing to the other side costs €70.

On the way home the arithmetic is similar. A bus or metro to the airport has to fit its own timetable, and the first departure of the morning may be later than an early flight allows. A car can be booked for any hour, including a pick-up well before dawn.

You do not have to pick one for the whole trip. Many itineraries work well with a transfer on arrival, when you are tired and loaded, and public transport during the stay.

Think about the first evening in particular. After a long flight, finding the right platform, buying a card and walking the last stretch with luggage can take more energy than the trip itself, while a driver holding your name at the exit takes all of that off the list.

The reverse also works: a cheap bus in on a light first day, and a booked car back to the airport on the last morning, when time matters most. Each leg is booked separately, and cancelling a booked transfer is free at any time.
