Paris'e biletler aldım doesnt sound like Turkish so much We prefer saying Paris biletlerimizi, Paris biletimi, Paris biletlerini aldım etc. you can say just the name of place without any suffix and you can add the subject suffixes to the word bilet. Paris'e biletimi aldım is also OK Paris'e (gitmek için) biletimi aldım. longer form If you say Paris'e biletler aldım. I understand that you have some tickets for Paris but you probably wont go Paris It is better expressing whom you bought these tickets for. And this is your choice saying Paris'e or just Paris. Both correct. Good luck!

paris'e biletler aldım=ı bought ticket to paris.so it isnt correct ı bought my ticket to paris=paris'e biletimi aldım

yes it is correct:)
