There has been a number of flights cancelled on the A380 at Auckland (Engineers have to be flown in etc) - Passengers are often not told until they get to the Airport.

This happened to me, and i opted to fly the next day. When i did check in the next day i asked them what happened and they said passengers were put on alternative flights (towards the end of the day/midnight) on QF! I never asked about compensation as i was going on holiday and i was trying to relax... J Ticket with F U/G.
