I am trying to make a simple date change to a QF Oz domestic sector. Its a BA issued ticket (xONEx). The friendly guy at QF Reservations absolutely refuses to make the requested date change and states that BA is the only airline that can make changes. He wouldn't listen to my comment that QF have happily made date changes previously. He also refused to listen to my comment that henis inconsistent with previous QF actions or the xONEx fare rules.

Have things recently changed regarding fare rules or is the QF phone rep wrong?

My option to phone BA is not currently viable given their IT issue and call centre volumes.
