Be careful gues, nowadays TK published new updated info, that tickets segments must be used ONLY according to the ticket issued. Segment can be cancelled from the reservation and reservation can stay alive , but when you apply to check in desk system will send warning and check in transaction will be prohibited due to segments were not used in a row. But in practice still I didn’t face such situation , but any way info is published.
