My Jetstar flight this morning was cancelled by Jetstar 35 minutes before takeoff at 0605 and Jetstar refuse to reimburse me. The NZ Consumer Guarantees Act says that if Jetstar cancels a service they need to reimburse passengers if a change is unsuitable. I was due to help a friend in hospital and a later flight was unsuitable. The Jetstar overseas based office was unaware of NZ Law and insisted they could not reimburse the fares. My PNR is CQKSNE.
