Well, the desk that deals with reservations at an out-station is typically the ticket office or, at best, the check-in desk. Both of which are landside.
Having flown TK from both YUL and BKK in the past 2 weeks, I would not have seen any other TK-manned desks airside at either airport (with the exception of the departure gate staff, which could deal with seating on the flight about to depart.)
