I have a policy that I will not fly Jetstar in NZ, based on reports of their delays and service. In fact my policy now even applies to when someone else is paying for the travel – if they really want me to attend their conference etc, then a non Jetstar airline mist be found.
Incidentially I have used them in Australia, where they have been good, It is just their NZ operations which seems to be so bad.
Whale blogs his experience at giving them a try. He has learnt the hard way.
