Let me add. Next time you have a schedule change of more than 15 min with TK, don't accept it right away! Let it be because until you accept it you have the flexibility to rebook or even cancel the ticket for free as this is considered invol. rebooking or cancellation due to sch.change. The moment you accept the retimed flight you loose this flexibility (and any cancellation or rebooking will have to be made according to ticket rules, i.e. is going to cost you). You may even change destination or origin within the same zone when you have a invol. schedule change like this.

The TK rebooking rules when you have a cancellation or invol. schedule change are very generous so no need to accept a retimed flight quickly.
