If Turkish Airlines cancels your flight, you have several options to consider. Firstly, immediately contact the Turkish Airlines Toll-free number +1-888-509-0323 / 1 (800) 874-8875 to understand the reason for the cancellation and explore alternatives. Turkish Airlines might rebook you on the next available flight or provide a refund if you prefer. Additionally, inquire about compensation for inconveniences caused by the cancellation, such as accommodation or meal vouchers. Keep all communication records and receipts for potential reimbursement. If necessary, you can also check your rights as a passenger under Turkish aviation regulations or consult consumer protection agencies for further assistance.
