The airport is 35km northwest of the centre. Havaş buses leave its city office for the airport (₺10) two hours before all flight departures and meet all incoming flights.
Most bus companies operate servises (shuttle minibuses) between the otogar (bus station; MAŞTİ) and the centre. City buses 2A, 2D and 152 run from the stop across the main road outside MAŞTİ to the Valiliği (provincial governor's building) in the centre. You need to buy a ₺4 kart (good for two rides) from the kiosk at the mosque by the bus stop. Going out to the otogar, the same buses leave from Inönü Caddesi in front of the Yeni Camii, where there's another kiosk selling the kart. A taxi to the otogar costs about ₺25.
Buses 1Ç, 1S and 4H run between the train station and the centre.
