The International Air Transport Association says global jet fuel supply could take months to stabilise, even if the Strait of Hormuz fully reopens.
IATA Director General, Willie Walsh, says disruptions to refining capacity in the Middle East mean supply challenges may persist.
He noted that jet fuel remains one of the biggest costs for airlines, accounting for a significant share of operating expenses.
Walsh explained that while crude oil prices may drop following a ceasefire between the United States and Iran, fuel prices for airlines could remain slightly elevated.
The disruption was triggered after Iran shut the Strait of Hormuz during the conflict, affecting global supply chains.
Although the reopening of the route has boosted airline stocks, IATA warns recovery in jet fuel availability will not be immediate.
