Business as usual for Jetstar, despite Air New Zealand taking a swipe at its airport discounts. 

Air New Zealand head Nikhil Ravishankar claimed airports are unfairly subsidising the Qantas-owned airline - on our most profitable air routes. 

BusinessDesk reports Ravishankar says that includes open-ended discounted landing rights and cost cutting deals. 

Jetstar CEO Stephanie Tully says they're just focused on running their own race. 

"The reality is, we've been trying really hard to make sure that we've got a great value proposition in the New Zealand market - and it's great that more Kiwis are giving us a go."
