I was in business class on this airplane for a 12 hour flight from Seattle to Istanbul. It was about the smoothest in the most luxurious flight. I think I have ever been on. The staff were excellent and extremely patient which I really appreciate it. Given the opportunity, I will certainly choose Turkish Airlines in the future. Job well done, hope to see you again in the future
