Higher oil prices due to the Iran war are increasing prices of jet fuel, which accounts for a big portion of airlines’ costs.

Brent crude oil rose near $100 per barrel on Thursday on worries about disrupted supply.

Spot Northwest European jet fuel prices were at $1,536 per metric tonne on Thursday, trading near an all-time high of $1,633 they reached intra-day on Monday.

Some airlines use futures and options to hedge against price increases. They also try to hedge against value changes in the US dollar, in which jet fuel is priced.

US airlines, which abandoned the practice of hedging against fuel costs, could be the hardest hit if the war is prolonged.

Below is a summary of how some of the world’s largest airlines are hedged:

Air France-KLM: The Franco-Dutch group said in February it had adjusted its fuel hedging policy to increase its total exposure over one year consumption to 87 per cent from 68pc. It said it had extended its hedging horizon to eight quarters from six and increased hedging percentages.

Air New Zealand: New Zealand’s flag carrier said in February it was hedging 83pc of fuel for the second half of its financial year and 46pc for the first half of the year to 2027.

It said the majority of its hedges were in Brent Crude, with some opportunistic Singapore Jet swaps expected in the second half of this year.

Cathay Pacific: Hong Kong’s flagship carrier said last year it was hedging fuel into the second quarter of 2027, covering around 30pc of costs until the second quarter of 2026.
