If the answer is "that's not how it works", I HUCA, politely. (Though that has not happened the last few times I've called.)

If yes, I say eg. "it's for one person, me, and I'm flying in J. The first flight is from YVR to IST on April 1st, 2023".

Provide the list of flights and dates, then let them see what the computer comes up with for choices, and if they need prompting on the exact flight(s) you want, tell them eg "TK 76 @" whatever the departure time is.

The better prepared you are, the better it goes, in my experience.
