For the February 16, 2026 TK1638 Munich–Istanbul 7:00 a.m. flight, I purchased a ticket directly through Turkish Airlines’ official website for my mother that included only a carry-on baggage allowance. Immediately after purchasing the ticket, I attempted to complete online check-in; however, the Turkish Airlines website did not allow me to proceed and displayed a message stating, “No seats available for online check-in.”
When we arrived at Munich Airport before the flight time and went to the counter, the agent told us that the system was closed and that since online check-in had not been completed, she could not be accepted onto the flight. No solution was offered, and she was denied boarding. As a result, the $762 I paid for this ticket was effectively lost.
I believe that being prevented from completing online check-in due to a system issue and then being denied boarding at the airport was entirely the result of Turkish Airlines’ own processes and system failure. Therefore, I request that my ticket be converted into an open ticket, that the amount I paid not be forfeited, and that the ticket be reissued in a reusable form. I also request that this situation be investigated, that necessary checks be made to prevent similar incidents from happening again, and that I receive a written response regarding the outcome.
