IST is on the far European side — 55 to 65 km from Kadıköy depending on the bridge. Here is every option with honest prices and times, and what we'd actually recommend for your situation.

Taxi estimate: official Istanbul taximeter tariff in effect since 1 July 2026 (opening 71,94 TL + 47,92 TL/km) over the 55–65 km route, plus the bridge toll. Istanbul uses a single tariff day and night — there is no night surcharge, so an 03:00 run costs the same on the meter as a midday one.
Option 1: Private transfer — our usual recommendation
A pre-booked transfer now costs well below a metered taxi on this route — a fixed 1.500–1.900 TL against nearly 3.000 TL on the meter — and the price is agreed before you ride, with the driver tracking your flight. For 06:00 flights — when you need a car at 03:00 — this is the only option we'd rely on.
How it works with us: send your date, time and pickup address on WhatsApp. We confirm a fixed price and the driver's plate number. You pay the driver directly — no prepayment.
Option 2: Metered taxi
Any yellow taxi will take the trip; expect roughly 2.700–3.200 TL on the meter including the bridge toll under the July 2026 tariff — the same price at any hour, since Istanbul runs a single tariff with no night surcharge. Use a taxi rank (durak), BiTaksi or Uber rather than hailing near the pier. Confirm the meter is running — the fare to IST is never a "flat 100 euro".
Option 3: Havaist airport bus
The Havaist İST-14 line leaves from the Kadıköy waterfront roughly every 30–60 minutes and costs about 250 TL — pay with Istanbulkart or a contactless card, no cash on board. It's comfortable and direct, but plan 90–120 minutes plus waiting time — and seats fill up at peak hours.
Option 4: Marmaray + M11 metro
The cheapest route, step by step: Marmaray from Ayrılık Çeşmesi (one M4 stop or a 10-minute walk from Kadıköy center) under the Bosphorus to Yenikapı; change to the M2 north as far as Gayrettepe; then the M11 straight into the airport. Around 60 TL with an Istanbulkart, but allow at least 100 minutes and expect stairs and three changes with luggage.
Which should you choose?
Early-morning flight or 2+ suitcases: pre-booked transfer, no question.
Midday flight, flexible: metered taxi or Havaist both work.
Backpacking on a budget: Marmaray + M11 — leave 3 hours before boarding.
Kadıköy → IST: quick answers
How much is a taxi from Kadıköy to Istanbul Airport?
Roughly 2.700–3.200 TL on the meter plus the bridge toll, under the official tariff in effect since 1 July 2026 (opening 71,94 TL + 47,92 TL/km over 55–65 km) — the same price day and night. A pre-booked transfer at 1.500–1.900 TL fixed is substantially cheaper.
How do I get to IST for a 06:00–08:00 flight?
The Marmaray and M11 don't start early enough, so it's a car: a pre-booked transfer at a fixed price (the driver comes to your door at 03:00 without complaint) or the taxi rank at nearly double the cost. Night roads are empty — the crossing takes barely an hour.
Where does the Havaist bus leave Kadıköy from?
From the Kadıköy waterfront by the ferry piers — the İST-14 line, roughly every 30–60 minutes, about 250 TL. Pay with Istanbulkart or contactless card; no cash on board. Allow 90–120 minutes plus waiting time.
Is there a night surcharge on the taxi to IST?
No. Istanbul abolished the separate night tariff years ago — a single tariff applies around the clock. What changes the fare is the route and traffic, not the hour.
