Incorrect, at least to an extent: I am able to change to different flights on the same date as originally booked without a reprice. I have also seen other posters confirm that they were able to change dates for the inbound without a reprice, although one poster did say that this was "at the end of the year" and that he only changed a ticket for 1 pax.
