I flew my kids and I to New Zealand last year and we basically went hungry on the flight to Coolangata. I did not know how the meals system worked and the agent did not tell me.
The phone sales person also told me that it was okay that my toddler was turning 2 during the vacation (i.e. he would still have the same rate and seating) but at Coolangata on the return the staff tried to make me pay the extra fare.
Obviously it was my first time with Jetstar and despite these kinds of communication issues, to tell the truth I was pretty happy with the rest of it.
Not so bad for the price. It is double to fly Air NZ or Qantas. No thanks to that.
