Air New Zealand is warning there could be more disruptions to come as wild weather, sickness and engineering issues have already disrupted some school holiday travel.
The airline has brought back its Covid or sickness flexibility policy to help to ease some of the pressure, with more than 2500 people swapping their tickets for credit already.
But what happens when the airline cancels on you?
A passenger Checkpoint heard from was booked to fly Auckland to Christchurch with Jetstar on Saturday. Her flight was cancelled and she was offered a full refund.
She then booked a $400 ticket with Air NZ as she had to get to Christchurch. The airline then cancelled the flight due to "operational issues" and offered an alternative booking or flight credit. There was no refund offer.
Air NZ declined to be interviewed and could not confirm how many flights have been cancelled in the past week.
