Thank you all. Finally I found a backpacker help me to talked to Turkish Airlines. I don't need to pay anymore, and can go to Istanbul, too. Lucky me:-D

Are you going back to Berlin? If yes, you can not do this.... You have to take all the flight IN ORDER!! Please help me,I can't type Chinese, but I can see it. I have a ticket (Return) from Berlin <--> Turkey(Adana), and the transpoint is Istanbul. But now I only want get in and out at Istanbul. I want give up the second route (Istanbul to Adana) I don't want to pay 40 euro to change the ticket. Is it possible? Will I get into trouble when I get in or leave Istanbul ?

喔Ya 我可以用義大利文的筆電打中文了 感謝樓上的救星 現在我知道我只能用這張機票在伊斯坦堡跳機 但不能回Berlin 為了省錢 我還是乖乖去Adana >< 只是在Adana好像找不到便宜住宿... 有辦法找到hostel嗎？？
