I completely agree with you. I flew business class with Turkish Airlines in July from Manchester-Istanbul-Karachi and I believe I had the same plane. Nothing worked. Manual reclining of the seat by the crew. Not a single word of apology. Instead they showed me attitude by saying “what can we do!”. I was deeply offended as I was being treated like a coach passenger.
Hence, I decided never to fly Turkish Airlines. You are right – Qatar, Thai, Emirates – provide pure luxury to their First and Business class passengers.
“Worst airline of the year”
