Of course, when one books a trip in "sardine class," one realizes that comfort is an expensive option. That having been said, the seats were in the seat no comfortable. However, this was more than compensated by the excellent (for coach) food service and the helpfulness of the crew. I also loved that Turkish Airlines does not nickle-and-dime you on luggage. Yes, I would go with them again.
