The boarding process is definitely not as smooth as some Asian airlines. But Turkish Airlines pleasantly surprised me with the quality of food - even vegetarian options - and the staff were so attentive and eager to please. Not the most comfortable seats, but luckily it was not a full flight and the staff were happy for us to spread and be comfortable.
