The flight was fine except half the bathrooms in economy class were out of order and taped shut. Turkish Airlines had changed or ultimately canceled the flight to Istanbul several times and the vendor that kayak uses to purchase the tickets then canceled our reservations without informing us. When I called for a boarding pass 24 hours before the flight, we found out that our reservations have been canceled and had to act quickly to get new reservations at double the expense… Using the same vendor who had gotten reimbursed for the original flights.
