İstanbul Airport ground transport

İstanbul Airport handles over 84 million passengers a year from a single vast terminal on the city's European side, roughly 40 km from the centre. There's no single train straight downtown: the M11 metro runs to Gayrettepe (change to the M2 or M7), the HavaİST premium coaches fan out across the city, and taxis and pre-booked transfers add bridge and motorway tolls. Crucially, neither the metro nor most services run around the clock, so late arrivals lean on the 24/7 HavaİST coach, a taxi or a transfer. This guide compares price, time and frequency for every popular destination.
