How to Get Refunds for Canceled Ferry Services?

In cases where ferry services are canceled by the operating company (İDO or BUDO), passenger ticket refund procedures are as follows:

  • Tickets Purchased Online: Refunds for tickets bought online (via website or mobile app) using a credit card are automatically processed and reflected on the respective credit card within 1 to 7 business days, without any action required from the passengers.
  • Tickets Purchased at the Counter or Agency: Passengers who purchased tickets with cash at the counter or through authorized agencies must go to the nearest terminal counter with their tickets to request a full refund.

Under What Conditions Are Ferry Services Canceled?

Decisions to cancel sea bus and fast ferry services in the Sea of Marmara and other sea routes are made jointly by vessel captains and operations centers. These decisions are typically made to ensure passenger and navigation safety. According to general maritime safety regulations, if wind speeds exceed an average of 30-35 knots (approximately 60-65 km/h) or wave heights reach a level that endangers the vessel's maneuverability and docking safety (generally above 2-3 meters), services may be instantly canceled for safety reasons. In such situations, disruptions can also occur on busy routes like Yenikapi - Yalova.

Ways to Get Instant Notifications for Service Cancellations

To stay informed about last-minute ferry service cancellations and avoid inconvenience at ports, it is crucial to enter your contact information (mobile phone and email) accurately and completely during the ticket purchase process. Ferry companies send automatic SMS notifications to registered numbers as soon as a cancellation decision is made (usually a few hours before the service). Furthermore, downloading the official mobile applications of İDO and BUDO and activating the "Allow Notifications" option is one of the most reliable ways to instantly learn about potential cancellations. This way, you can access up-to-date information without having to wait at piers like Yalova or Yenikapi.
