How much does public transport cost in Istanbul (metro, tram, bus, ferry)?

Route from Taksim to the airport: take tram T1 to Kabataş, then the funicular up to Taksim, then metro 3 stops to Gayrettepe, transfer to the airport metro line (exit from the last car for the transfer). Total cost is around 150 lira.

According to the latest reports, a single Istanbulkart ride on buses, trams, and the metro costs about 42 lira. A city ferry/sea tram ride is around 69 lira.

Buses and trams do not run 24 hours — check schedules in advance. The metro operates around the clock on certain days.

A bus ride from Sabiha Gökçen Airport to the city center costs around 480 lira per person (not including the Istanbulkart). It's the cheapest option, though uncomfortable with large luggage.

The metro from Sabiha Gökçen Airport to central Istanbul costs roughly 160–200 lira per person. One Istanbulkart can be shared — the card itself costs 165 lira and can be topped up to 2,750 lira.

Cash and foreign currency are not accepted on Istanbul buses — payment is only via Istanbulkart.

A single metro or tram trip costs around 42 lira. Marmaray commuter rail and ferries are more expensive. The balance on an anonymous (non-personalized) Istanbulkart is non-refundable.
