From
Sabiha Gökçen Havalimanı station, the last stop on the M4. Buy or top up the İstanbulkart before the gates

Do not tap a bank card. The reader takes it and charges the single-use price, TRY 65, against TRY 46.20 on an anonymous İstanbulkart bought before the gate.

Fifty-two minutes end to end: the airport is the last stop and Kadıköy the first, so every ride is the whole line, with 21 stops between.

Sunday to Thursday the last train is 23:59. Land later and it is the E-10 bus (00:15, 01:05, 02:25, 03:30), a Havabüs coach to 01:30, or a meter taxi. Friday and Saturday nights the metro runs through instead, every 30 minutes at double fare.

It does not cross to Europe. For Taksim change at Ayrılık Çeşmesi to the Marmaray, then to the M2 — three trains — or take the Havabüs coach direct.

Six and a half times cheaper than the Havabüs coach to the same square, and no slower.

Every fare on this page is İBB's tariff of July 2026, the second revision this year; expect the figures to have moved again and check the fare at the gate.

This line only exists at night. Miss the 03:30 and the next public transport is the metro at 06:00 or a Havabüs coach for delayed flights, if one is running.

The cheapest thing that moves after the last metro on Sunday to Thursday nights — TRY 92.40 against TRY 300 on the Havabüs coach — and it takes 87 minutes.

The night fare is an open question: the tariff doubles bus fares between 00:30 and 05:30 unless a decision says otherwise, and none is published for this line. Budget for TRY 184.80 on the 01:05, 02:25 and 03:30 departures.

Pay with an İstanbulkart: a bank card is charged the single-use price, TRY 120.

No departures on the night from Friday to Saturday. The M4 runs through that night, every 30 minutes at double fare.
