What do you mean? Any rebooking/reissue of the ticket before travel has commenced will be subject to repricing of the ticket - there is nothing new about this nor anything TG is making up. Rebooking after travel has commenced should on the other hand be subject to historical prices, i.e. no repricing of the ticket - the issue is if TG will honor that rule.
