Domestic flights are being re-timed all over the place today. I have had flights in 10 days time auto-cancel by AirNZ even when there were same day options at a different time. Not possible to fix anything on line and have to waste the call centre's time to retime bookings. One of which they have re-booked me on to a flight that already no longer exists.
Will leave it all now, for a couple of days, to see where flight times actually settle to.
