Istanbul airport wait (question)

Hi all,

Hoping you can help me out, I will be flying into Istanbul airport at the end of next month and will be waiting for my daughter (haven't seen her in almost a year) who will be arriving from another country. I will have to wait about 4 hours for her flight to get in (and the same on our way back to our respective countries).

My question is, where can I comfortably wait for her until her plane arrives (in arrivals?) and also, when we leave (after security, international departures?).

Any advice will be very greatly appreciated!!
