Australias Qantas Airways , Scandinavias SAS and Air New Zealand, announced airfare hikes on ​Tuesday, blaming an abrupt spike in the cost of fuel caused by the Middle East conflict.

Jet fuel prices, which were around $85 to $90 per barrel before US-Israeli strikes on Iran, ‌have soared to between $150 and $200 per barrel in recent days, New Zealands flag carrier said as it suspended its financial outlook for 2026 due to uncertainty over the conflict.

The war, which disrupted shipping via the worlds most vital oil export route, has sent oil prices surging, upending global travel, pushing airline tickets on some routes sky-high, and sparking fears of a deep travel slump that could lead to widespread grounding of planes.

“Increases of this magnitude make it necessary to react ​in order to maintain stable and reliable operations,” an SAS spokesperson said in a statement to Reuters, adding it had implemented a “temporary price adjustment”.

The largest Scandinavian airline said last year it ​had temporarily adjusted its fuel hedging policy due to uncertain market conditions and that it had no fuel consumption hedged for the following 12 months.

While ⁠several Asian and European airlines, including Lufthansa and Ryanair, have oil hedging in place, securing a part of their fuel supplies at fixed prices, Finnair warned that even the availability of fuel could ​be at risk if the conflict dragged on. Kuwait, a major jet fuel exporter to north-west Europe, has faced output cuts.

“A prolonged crisis could affect not only the price of fuel but also its ​availability, at least temporarily,” a Finnair spokesperson said, adding that it had not seen this happening yet. It had hedged over 80% of its first-quarter fuel purchases.

Airspace chaos in the Middle East

Highlighting the airspace chaos in the Middle East, planes arriving in Dubai were briefly placed in a holding pattern on Tuesday due to a potential missile attack, flight tracking service Flightradar24 said on X. The planes eventually landed.

Qantas said in addition to increasing international fares, ​it was exploring options to redeploy capacity to Europe as airlines and passengers seek to evade disruptions in the Middle East, where drone and missile fire have curtailed flights.

Airfares have soared on Asia-Europe routes ​due to airspace closures and capacity constraints, and Hong Kongs Cathay Pacific Airways (0293.HK) said on Tuesday it was adding extra flights to London and Zurich in March.

Air New Zealand said it had raised one-way economy fares ‌by NZ$10 ($6) on ⁠domestic routes, NZ$20 on short-haul international services and NZ$90 on long-haul, with more adjustments to prices and schedules possible if jet fuel costs remain elevated.

Hong Kong Airlines said on its website it would raise its fuel surcharges by up to 35.2% from Thursday, with the sharpest increase on flights between Hong Kong and the Maldives, Bangladesh and Nepal.

Airline shares stabilize after selloff

Some airline stocks rose and oil prices fell to around $90 a barrel on Tuesday from a high of $119 on Monday after US President Donald Trump said on Monday the war could be over soon.

When markets opened in Europe, airline shares ​were up between 4% and 7%. In Asia, ​airline shares showed signs of stabilising, with ⁠Qantas closing up 0.5%, Korean Air Lines (003490.KS), opens new tab rising 3% and Cathay Pacific (0293.HK), opens new tab up 3.6%. All had recorded sharp declines on Monday.

Fuel is the second-largest expense for air carriers after labour, typically accounting for a fifth to a quarter of operating expenses.

Conflicts shrinking available airspace

In addition to high fuel costs, ​tightening airspace also threatens to derail the global travel industry, as pilots reroute to avoid the Middle East conflict and capacity on popular routes ​fills up.

Emirates, Qatar Airways and ⁠Etihad typically jointly account for about one-third of the passenger traffic between Europe and Asia and fly more than half of all passengers from Europe to Australia, New Zealand and nearby Pacific Islands, according to Cirium.

European airlines have already struggled with the shortage of available airspace created by the war in Ukraine, with many avoiding Russian airspace and flying longer international routes. Now, with even less available airspace, they ⁠say their business ​has become even more challenging.
