Dec 8 (Reuters) - Air New Zealand Ltd on Thursday increased its earnings forecast for the first half of fiscal 2023, helped by strong travel demand across its domestic and international networks and a decline in jet fuel prices.

The company now expects earnings before tax and other significant items between NZ$295 million ($187.5 million) and NZ$325 million for the first half of fiscal 2023, compared with its previous outlook of NZ$200 million to NZ$275 million.
