May be they haven't added the right fare bucket yet? As well until the announcement which is happening now there is no fix dates on anything, so is just an indicative schedule so don't want too many confirmed upgrades if need to shuffle things around. And also changes based on loads.
Also if blocked out on Raro flight is that for crew positioning? Before schedule fully going again. Don't know what Raro's border is as they are different to NZs border.
