Jetstar has been doing its darndest to shift perceptions among some Kiwis travellers that the low-cost airline is cheap for a reason, with its last campaign offering $24,000 worth of flight vouchers and drawing attention to the fact that, despite a reputation for unreliability, it was named New Zealand’s most punctual domestic airline in 2013. And it’s backing itself once again, offering a $25 voucher to all passengers if a domestic flight during the next eight days arrives more than ten minutes later than scheduled.
