Istanbul is several networks at once: metro, tram, bus, ferry and the Marmaray rail under the Bosphorus. The M11 metro is the airport line. Istanbul Airport’s own page describes it as the Gayrettepe–Istanbul Airport metro, later extended, with the Halkalı section opening on 20 June 2026. The line ties the airport into the wider rail map, including a change toward the rest of the metro. It is a fast public route into the European side. It is not a stop at every hotel, and it does not cross to the Asian shore by itself.
Sabiha Gökçen, the city’s other airport, is on the Asian side and uses a different metro, the M4 toward Kadıköy. A transfer booked for Istanbul Airport will not be waiting at Sabiha Gökçen. Ferries, trams around Sultanahmet and the M2 through Şişli are how the city feels once you are in it. They are a pleasure with a day bag. They are a project with luggage.
The airport sits well north of the historic peninsula, in Arnavutköy. Sultanahmet, Taksim, Beşiktaş and a hotel on the Asian side are four different rides. The M11 can begin the European ones. The car is the one that ends at the door you named.
Hours, stops and fares on public transport are set by the operator and they change. What is written here is the shape of the network, not a live timetable. Check the operator on the day you travel.
Booking the transfer with Buddy on Move is the reliable way through Istanbul Airport, because the arrangements are finished before you land. You are not comparing a rank of cars at the kerb, and you are not guessing a meter. On this page you set the airport and the other stop, a hotel, a home or an address, then the date, the time and the vehicle. The fare shown is the full price for that ride. Checkout does not add a booking fee, and the amount stays the same after you pay. If you need the return as well, you add it with its own time and you still see one total before any payment.
After you pay, Buddy arranges a driver for that transfer. The meeting place at the airport is the arrivals meeting point. This is not a hunt for a name on a scrap of paper. The driver's name, phone and vehicle appear on the trip before pickup, so you know who you are walking toward. The same booking works in the other direction, from your door back to the airport, which is often the early-morning ride public transport is worst at. Add the flight number when the airport is the pickup. Buddy uses it to coordinate if the arrival time changes, and does not follow the flight on a live status feed. The driver waits up to 60 minutes after the scheduled landing.
The booking itself is short on purpose. People and bags, so the vehicle you choose actually fits. A date and a time. A stop you can point to. There is no second negotiation when the car arrives, because the fare was already the fare. If the plan changes, you can cancel up to 24 hours before pickup for a full refund of the transfer fare. The cancellation page is there if you want the conditions in full. The form only offers pickup times that are far enough ahead to arrange.
Public transport remains a good choice when you are light on luggage, inside the hours the trains or buses run, and close to a station. Buddy is the easy choice when any of those is untrue: a family, a late flight, a resort off the line, or simply an address you would like to reach without planning three connections. You confirm the fare, you pay, and a driver is arranged for that one ride.
