We love to fly with Turkish Air and have arranged our own flights with them. We agree, best food in the air. That being said, everyone has a different experience with getting seat assignments. I have never had such a hard time getting seat assignments as I have had with our upcoming flights. Our first time flying them 8 years ago was a breeze. Not so this time. If you google Turkish seat assignment issues, you will see many, many people have had a very hard time and can't figure out why. Your TA is probably hitting the wall that we have hit for months, but he should communicate this to you. We finally got assignments for our first and most important flight, but not able to get the European connection. We have spent many hours on this and will address the second leg of the trip at the airport since it is a short connection. Some have said if you install a mobile Turkish App on your phone and then submit a customer report of issue, that will get you what you need. There are also helpful blogs from various frequent flyer sites that at least let you know you are not alone in dealing with issues and give some helpful advice. One very important thing you need is the Turkish ticket number. Our flights start with a United flight and even United was unsuccessful in getting our Turkish ticket number. Our situation is different because we are using Frequent Flyer miles for our flights so United is the one who booked our flights. The supervisor for United even tried for days to get Turkish ticked number and couldn't. I hope you get resolution because even with all of these problems, we are still looking forward to our Turkish flights.
