I have booked a return flight with Turkish airlines for my family (myself, my wife, one 6-year-old kid and another infant, 10 months old), and we used the outbound trip.
Now for the return, my wife got some problem with paperwork and cannot make the return flight. So we've decided that she will stay (with my parents, it's our hometown actually) until the visa is done, and she will stay with the younger child (the older one has to go back to school and I have to go back to work, and each of us cannot accompany both).
When I when to booking management to cancel this return trip online for my wife, I could do that just fine. But I noticed that for the smaller child I cannot do anything with her reservation, i.e. I can't cancel her ticket, because she's attached to me! (I'm marked as passenger with a baby -- either I cancel mine and she will share the same effect, or she will stay in the PNR no matter what).
So the question is, when I arrive at the airport to do the check-in, can I just check in myself and the older kid? I don't want the scenario where they issue all 3 boarding passes for 3 people, then my small one is no-show at the gate, or can it be even worse: I might be denied boarding as they can ask 'where is the baby you're supposed to carry with you'?
(If I try to check in online it will show "check in for 2 people". My infant child has a ticket number of her own too).
