The best way though to cancel tickets and place a request for a refund is through a phone call. This is without a doubt a great way to personally associate with the airline's representative by calling Turkish Airlines' flight cancellation number. You can straightforwardly speak to a Turkish Airlines customer support agent any time as they are available nonstop. They are the perfect people to assist you with the cancellation and refund requests. You simply need to furnish them with your booking confirmation and travel details. When the expected information is given to them your cancellation cycle will then be initiated and steps to get you a refund will be taken. Turkish Airlines will also send a flight cancellation confirmation email to the customers after the whole interaction is finished.
