Air New Zealand is slashing 5 per cent of its flights, or about 1100 services, for two months as the ‌Iran war sends jet fuel prices surging and disrupts travel.

The New Zealand carrier led ‌other airlines including Qantas Airways, Scandinavia’s SAS and Thai Airways in announcing airfare hikes this week, blaming an abrupt spike in the cost of fuel that has rattled the global aviation sector.

The Middle Eastern conflict has forced many airlines to cancel flights to and from the region or use alternative routes due to drone and missile fire that has severely curtailed airspace and caused the biggest aviation industry crisis since the pandemic.

Oil prices climbed on ‌Thursday after Iraqi ‌security officials said Iranian explosive-laden ⁠boats had hit two fuel oil tankers amid other global supply disruptions and Iran said the ​world should be ready for oil at $US200 a barrel.

Air New Zealand CEO Nikhil Ravishankar told Radio New Zealand that about 44,000 customers of the 1.9 million flying until early May would have to be rebooked due to domestic and international flight cuts.

Airports servicing areas such as popular New Zealand winemaking region Marlborough and west coast city New Plymouth would have reduced services in coming weeks.

Fewer long-haul flights would be cut, ⁠Ravishankar said, as the airline’s US routes had become a more popular stopover on ‌the way to ​Europe since widespread Middle Eastern airspace closures.

“People want to get to Europe still, and over the US airspace we can get them into ​Europe, and that’s ‌what we’re focused on doing,” he said.

Air New Zealand’s shares were down 1 per cent on Thursday, in line with drops in Cathay ​Pacific, Qantas Airways and Japan Airlines.

On Wednesday, two drones fell near Dubai’s main airport – the world’s busiest hub for global passengers – and Bahrain evacuated some planes, as attacks on infrastructure across the Gulf continued to wreak havoc on air traffic.

The war has also ​disrupted ​shipping via the world’s most vital oil export route, ​sent oil prices surging and upended global travel, pushing airline tickets on ‌some routes sky-high, and sparking fears of a deep travel slump.

Travellers are also scrambling to switch to carriers that avoid Middle East airspace, with Thai Airways saying it was already taking on board more passengers to and from Europe.

Cathay Pacific has cancelled its flights to Dubai and Riyadh until the end of March. It is instead adding more services to London and Zurich, taking advantage of a spike in demand for Asia-Europe flights that ​avoid the Middle East.
