Holiday travellers have had their plans disrupted after a Jetstar IT glitch delayed transtasman flights for up to an hour and a half today.

Flights between Australia and New Zealand had been affected, a Jetstar spokesman said.

Passengers were experiencing delays of between an hour and an hour and a half.

"Our systems are now coming back online and flights have departed this morning.

"We apologise for the disruption these delays have caused our customers," the spokesman said.

The outage affected applications and systems used by airport and flight crew to prepare for flights, slowing down our operations this morning, he said.
