Why nobody tells you about the buses
Search for how to get out of Sabiha Gökçen and you will be told about the coach, the metro and a taxi. The municipal bus network barely gets a mention, even though it reaches more of the city than either rail option and costs the same single fare as the metro.
Part of that is presentation: İETT buses are city buses, not airport services. There is no luggage hold, no English-language ticket desk and no branding that says airport. But if you are travelling light, going somewhere the metro does not reach, or landing at three in the morning, they solve problems nothing else does.
Which lines actually serve the airport
Around ten lines call at Sabiha Gökçen, mixing İETT city buses, airport-specific SG services and regional operators. These are the ones worth knowing:
| Line | Goes to | Worth knowing |
|---|---|---|
| E-10 | Kadıköy via Kurtköy | Runs 24 hours, every 15 minutes — the late-night answer |
| E-11 | Kadıköy | Second Kadıköy option |
| E-3 | Levent (European side) | Rare direct link across the Bosphorus by bus |
| E-9 | Asian side districts | Local coverage |
| 16S | Asian side districts | Local coverage |
| SG-1 | Kadıköy | Airport line listed by İETT — not the Havabüs coach |
| SG-2 | Taksim | Airport line listed by İETT — not the Havabüs coach |
| 132H | Pendik high-speed rail station | Every 2 hours, 06:50–21:50 — for YHT connections |
| 122H, 130H | Local Asian-side routes | Neighbourhood coverage |
| 250 (UlaşımPark) | Gebze, Körfez, İzmit | Regional, every 30 min around the clock |
The E-10 is the one to remember
If you take one thing from this page, take this: the E-10 runs between Kadıköy and Sabiha Gökçen twenty-four hours a day, at roughly fifteen-minute intervals.
That single fact makes it the most useful line at the airport, because it covers exactly the gap the metro leaves. The M4 shuts around midnight. Sabiha Gökçen keeps handling arrivals well past that — it is a low-cost hub, and low-cost schedules do not respect sociable hours. Land at 01:30 and the E-10 is running while the metro is not.
It is slower than the metro and it sits in traffic, but at two in the morning there is very little traffic to sit in.
SG-1, SG-2 and Havabüs are not the same thing
This is the single most confusing thing about Sabiha Gökçen ground transport, and it trips up a lot of travel writing — including, until we checked, some of our own route pages.
İETT lists airport lines coded SG-1 (Kadıköy–Sabiha Gökçen) and SG-2 (Taksim–Sabiha Gökçen) on its own route system. Havabüs is something else: a private airport coach brand operated by Havaş, running its own vehicles on similar corridors at a much higher fare. Plenty of sources treat the SG codes as Havabüs line numbers. They are not the same service.
In practice you can tell them apart on the ground without knowing any of this. The Havabüs coach is a large branded intercity vehicle with a luggage hold underneath and a fare in the hundreds of lira depending on destination. The municipal bus is a city bus you tap onto with an İstanbulkart for ₺46.20 and stand up in.
| Municipal bus (İETT) | Havabüs coach | |
|---|---|---|
| Fare | ₺46.20 İstanbulkart tap | ≈₺230–270 Kadıköy / ₺370–440 Taksim |
| Payment | İstanbulkart only | Cash, card or İstanbulkart |
| Luggage | With you, no hold | Hold underneath |
| Vehicle | City bus | Branded coach |
| Seat | Not guaranteed | Guaranteed |
The luggage problem, stated plainly
City buses have no luggage compartment. Your case travels in the aisle or in the standing area by the doors, and at busy times that means apologising to people for forty minutes.
This is the real reason the buses stay a niche option rather than the obvious one. With a backpack, they are excellent. With two large suitcases, they are a bad idea regardless of what they cost — and we would rather tell you that here than have you discover it on a packed E-10.
When a bus is genuinely the right call
And when it is not: two large cases each, small children, a cruise sailing or a connecting flight with no slack in it. On those trips the fare difference buys something real.
- Landing after midnight with hand luggage — the E-10 runs when the metro does not.
- Heading somewhere on the Asian side that the M4 does not serve directly.
- Connecting to the high-speed train at Pendik — the 132H exists for exactly this.
- Travelling on a tight budget and not in a hurry.
- Continuing to Gebze, Körfez or İzmit — the regional 250 runs every 30 minutes around the clock.
Frequently asked
Are there city buses from Sabiha Gökçen airport?
Yes, around ten lines serve the airport, including E-10 and E-11 to Kadıköy, E-3 to Levent on the European side, and 132H to Pendik high-speed rail station. They cost a standard ₺46.20 İstanbulkart fare.
Which bus from Sabiha Gökçen runs 24 hours?
The E-10 between the airport and Kadıköy runs around the clock at roughly 15-minute intervals. It is the most useful line at Sabiha Gökçen because it covers the hours when the M4 metro is closed.
How much is the bus from Sabiha Gökçen?
₺46.20 with an İstanbulkart, the same as the metro. That is roughly a fifth of the Havabüs coach fare to Kadıköy. İETT buses do not accept cash.
Is SG-1 the same as Havabüs?
No. SG-1 and SG-2 are airport bus lines listed by İETT, the municipal operator, while Havabüs is a private coach service run by Havaş on similar corridors. The coach costs several hundred lira and has a luggage hold; the municipal bus is a ₺46.20 İstanbulkart tap with no hold.
Can I take a bus from Sabiha Gökçen with large luggage?
You can, but city buses have no luggage compartment, so your cases stay with you in the aisle. It works with hand luggage or a backpack and becomes unpleasant with two large suitcases, especially at rush hour.
How do I get from Sabiha Gökçen to Pendik train station?
The 132H bus links the airport to Pendik high-speed rail station, running roughly every two hours between 06:50 and 21:50. Check the current timetable before relying on it, as the gaps between departures are long.
