Two return Jetstar flights from Wellington to Auckland have been cancelled today, frustrating dozens of passengers.

The cancellations, blamed on crew being ill, come on the final day of the school holidays when many travellers are trying to return home.

Angry passengers told the Herald some had been left out of pocket and some faced lengthy waits and longer routes, as a result of the 3.10pm and 6.20pm flights from Wellington to Auckland being cancelled today.

A Jetstar spokesman said they did not have enough staff to fully crew two return flights between Wellington and Auckland on Sunday.

"We understand this is very frustrating for customers on these two cancelled flights and we've apologised to customers.

"We are putting customers on other flights and will get them to their destination as quickly as possible," the spokesman said.

Passengers had been offered refunds, offered flights for later today or on Monday or re-routed via Christchurch.

However Aucklander Dinithi Seneviratne said the two other flights for Sunday were booked out within minutes of being notified her 1.35pm flight had been cancelled and she was told by the call centre a refund would take 15 working days to process.

She said she received a "parrot-like apology" from a call centre worker who said they could not do anything.

So instead her and her daughter have had to shorten their trip to Wellington and will fly out on Monday morning instead.

Seneviratne had also looked at flying Air New Zealand but said there were no flights available.

"It was really abrupt. Just we are sorry - there is a crewing error. We don't have enough crew to fly and so you will just have to deal with it."

Angrez Singh told the Herald he had been due to fly from Auckland to Wellington at 1.35pm, which was one of the flights cancelled last night. After being told there were no flights available today, Singh booked a flight with Air New Zealand which cost him another $100.

Jetstar said it would also pay for accommodation for up to $150 for passengers who could not fly until tomorrow and did not live in the city they were stranded in.

Passengers were notified by text and email last night at about 9.30pm.
