You might try contacting a sales office for this and please report back your experience if you do so. By the way, seat selection is free during OLCI.
This post is a bit old, so so I wonder if seat selection indeed still free during OLCI for economy class passengers? This page
https://www.turkishairlines.com/en-i...ions/check-in/ says that seats are assigned randomly during check-in and they cannot be changed once
the boarding pass has been printed. So, does it work the same way as with Iberia or BA, for instance?
