My in-laws have been travelling from Spain over the last few days to arrive in Auckland. They were due to fly jetstar to Napier after this arduous ordeal. I joked when going to pick them up that they might cancel as they did with me the last time I flew with them. (I NEVER FLY JETSTAR). I got to the airport and they had cancelled. They offered a bus from auckland to Napier. Awesome journey. They said tower issues. What they mean is that they were late and couldn't get out in time.
