Does TG reprice based on historical fare for a change on the return date (same routing) on a round-trip ticket when the outgoing segment has been flown? E.g. BKK-CPH RT on a non-flex economy fare, changing the CPH-BKK flight date after flying BKK-CPH.
I tried searching this thread and also through the general site and only found info on other airlines and not specific to TG. TIA.
