It's hard to understand why the staff at Turkish Airlines (not the flight attendants) are so impolite and careless. My mother was traveling from Erbil to Amsterdam with a layover in Istanbul. When she reached the gate, it was already closed ahead of schedule. She had been delayed previously by the same airline, and when she got to the gate, they dismissed her rudely. This is simply unacceptable. Why is there such a lack of courtesy? They should at least consider her age and language barrier. I hope this improves soon. I will not fly with Turkish Airlines again or suggest it to anyone. My mother was crying at the airport, and no one helped her.
