Follow these instructions on a desktop computer or the Turkish Airlines mobile app. The process takes less than five minutes.

  1. Log in to your account. Open turkishairlines.com or launch the mobile app. Use your booking reference (PNR) and the passenger’s last name to access the reservation.
  2. Navigate to “My Trips.” Once logged in, locate the “My Trips” or “Manage Booking” section. This page displays all upcoming flights associated with your account.
  3. Select the flight you wish to modify. Click on the specific reservation that contains the online check‑in you want to cancel.
  4. Find the check‑in status. The flight summary will show a badge such as “Online Check‑in Completed” or “Checked‑in.” Click the badge or the adjacent “Details” link.
  5. Choose “Cancel Check‑in.” A button labeled “Cancel Check‑in” or “Undo Check‑in” will appear. Confirm the action when prompted. The system will revert the passenger’s status to “Not Checked‑in.”
  6. Save the changes. After cancellation, you will receive a confirmation screen and an email confirming the reversal. The reservation is now ready for a new check‑in.
