The usual way to get from Istanbul to Çanakkale is to take a direct bus from the Büyük or the Harem otogar (bus station). That's especially true if you stay somewhere in the "center" of Istanbul. But what if you arrive by plane at Atatürk airport somewhere between 5 PM and 2 AM (exact arrival time not yet known)?
I imagine that one solution would be to take a taxi, shuttle or even public transport to one of the above mentioned bus stations and to proceed from there. But now I wonder if there is no other option from the airport? Aren't there direct buses to Çanakkale leaving from the airport, or nearby? In case of a late arrival you would save some precious time by not having to go to one of the bus stations first.
I am looking for a "public-transport" solution. Taxi rides to bridge shorter distances are okay, but not a private taxi ride for the whole distance.
