Never flown TK before but considering flying business for our trip from IAD to Italy next year - both segments go through IST. In looking at their site though, there is still no place to put our KTNs either in the reservation itself or in your personal account information.

And again I apologize for asking this again but I figured in the last 4 or 5 years that some of these older threads were made, maybe it had been fixed.

The only thing I've read says that you can just add this during check in? Is it really that easy? I've had GE for the last 10 years or so and honestly I just assumed it had to be on your reservation a certain amount of time before check in so that it could make it to the CLEAR/PreCheck systems.

Thanks in advance for any current information.
