When I went to AsMo for one of my trips that happened to the lady in front of me. She was upset and wanted to stay there. I overheard and told them I would gladly take the upgrade. She then changed her mind but said they should comp tickets or give her some other compensation since she was staying somewhere other than where she booked. To some, an upgrade is just not enough. So happy for your sister though. Loved my AKL stay.
